I don't know if many people knows it on this forums or not but steam is in a kind of battle with Epic
but i kind of missing GOG in this fight, why are you guy's not doing anything

my suggestions,

1.
People that bought titles on Steam should be possible to switch to GOG they already bought a game licence on steam
it should not be that hard or difficult to activate a game licence on GOG of the same title

2.
let those 2 battle and you play smart, try to rail in more titles If i recall Epic not have a DRM use this to get titles on GOG

3.
try to give the customer more privacy this will be a hot topic in the future mark my words, if you company leads it will do you good in the long run

PS,
one last thing i don't know if you guy's know but the current popup sign in is messed up when i try to copy/past passwords the popup is lost this is very unhandy for people that use 35+ strong password generators codes to login

Great idea, man!

?
store is not losing anything they licence was already bought and it's a cheap way of pulling new customers into your store.
is that not what front-stores want more then anything?.

Sure, the license has been paid for - to Steam and the developers/publishers...but not to GOG.
But GOG would have all the work with customer complaints, support questions, the costs for providing the download-servers...

Congratulations, you just invented GOG Connect!

Who says they are not doing anything? Considering Epic's "fight" is with Steam, GOG may as well be working out deals with publishers/devs/Epic so that Epic exclusivity doesn't include GOG (or for less time than a year)... and we wouldn't know about these discussions. I don't think your other suggestions would work, sorry.

EDIT: In my opinion, the best idea GOG had regarding PC stores/platforms "battle" is GOG Galaxy 2.0. Even if it's meant to work with all of them. But that will give GOG a lot of visibility and good publicity.

I don't know what's go's around closed doors but it's silent on GOG side i watching youtube news sites that his information on the latest very closest and i not seen GOG in like ages on it's coverage, so no story. None of my Steam games get converted to GOG so it's at a very early =(

most of the time the publishers of the games choose to put steam on front then like ages later GOG
but with the events like Epic marketing shifting for customer and publisher alike.
also i have personal issues with steam so i can go to epic or GOG i rater go to GOG to be honest
but hey if you think you are being missed out somehow do to "loyalty" you have a lot to learn about economics.
for instance money is only loyal to it's spender.

Problem is that if GOG takes your suggestion, doesn't it just keep incentivizing publishers to do that? Epic Fail Store (EFS) is not a DRM-free store any more than Scheme is, so I am not seeing how they are disrupting anything in favor of the DRM-free customer yet. If GOG gives freebies to Scheme customers (or EFS customers, for that matter), then how does that make publishers put games here any faster? If anything, there is even less benefit to publishers putting games here since they wouldn't even be getting a new sale out of it! Here is where loyalty comes in: building and keeping an audience. This is particularly important when catering to a niche market as the store needs to be able to keep being mindful of its audience.

Your argument seems to be that by giving freebies to people who bought on Scheme, it can build GOG's audience. Maybe, maybe not. But what it certainly does is alienate the existing audience who bought the games on GOG.

If Customer A buys the game on GOG, and Customer B buys the game on Scheme but then gets it free on GOG, what kind of message does that send to Customer A?

to my personal nothing i not see a store like a personal friend or brand. but like a store that sells a product like GOG sells game titles.

where you see alienating i see more customers which means that publishers see is missing market share
in turn gives you not only more choose but also faster new titles and better titles.

and no it's not a freebie the licence are already bought, it's not that they are given for free i don't think a store like GOG would care much if their data transfer go's from 5 peta byte per month to 8 Peta Byte if more potential buyers are on platform. understand that people on a specific platform is like golden.
google see's each user worth of 200$ even if they never ever bought a product of google the use of google along is worth it.

so that being said, i think any store should like accept ship jumpers with open arms.
even if you feel like you missing out on something you get befit on the long run from it

Let's talk about Economics. GOG pays developers for every copy sold at market price. When GOG does a sale, their own cut is lesser sue to reduced prices. When games are given away, GOG either has to license the keys given away for free (if the dev/pub approves) or pay for the keys given away. Therefore, giveaways are a loss leader for GOG. To giveaway mass amounts of title to users and essentially reward them for supporting GOG's competition in a large scale would literally destroy GOG financially.

GOG will accept you with open arms. No one will turn you away here. But you won't get any more than normal for free. After all, GOG sells games. If you bought games elsewhere and then demanded them on GOG, they'd get zero profit, and you'd have zero incentive to buy on GOG directly in the future when you could buy on Steam and get all the "steam social media goodies" and still keep a second DRM free copy for yourself. GOG would be bankrupt in a matter of hours.

You're worth that much to Google because of data tracking/mining/metrics and targeted advertising. Don't be fooled into thinking they get nothing from you.

You're vastly underestimating the cost to GOG of giving away free games. Paladin181 covered some of it, but there are also the costs associated with bandwidth for all those people DLing free games, support requests, etc. (mentioned earlier by BreOl72) If you think it's so easy as just giving free keys to people that bought games elsewhere and there would be such a great benefit to the store, why haven't GOG already done this? Or Steam? Or Origin? Or Epic? Surely they have marketing and sales analysts that would have thought of this long before. The answer is because it's not economically feasible.

Then I will spell it out more.

The message sent to Customer A in that situation is that they are less valued than Customer B.

Do you feel it is a wise economic decision for a business to make some customers feel less valued? Especially when those customers are the ones who supported the store up to this point?

How? How is there more publisher market share in that scenario? The publishers literally would have the exact same amount of sales to customers. So what if some customers bought the game on Scheme and then got a free copy on GOG. That doesn't give the business any more profit from the customer. How is the customer (who already paid for the Scheme copy) representing any more market share by the fact they also claimed a free copy later?

Use whatever terms you like, but the problem I am pointing out to you remains the same. The customer bought ONE license. That they then go onto GOG and can also access a version of what you are calling the same license, is not providing the publishers with ANY more market share. The number of copies the customer bought remains ONE. Remember, we are talking about publisher market share.

Why would anyone buy anything from GOG then, if you could always get both the Steam version and the GOG version, if you buy from Steam instead?
