Oh I didn't know about that!

You're actually talking too generally here, because there are plenty of customers who didn't abuse the system and still miss these options - they didn't make that bed they have to lie in now. And it's not as if that decision not to offer DRM-free installers alongside Steam keys was without alternative. There are still many developers who trust their customers enough to do it. Any system that's exploitable will be exploited by some, and if those publishers actually switched from one system to the other just because they didn't expect the first to be exploited by some, like you claim, then they must have been pretty naive to start with, which I don't really buy into. The whole concept of DRM-free is based on the idea that you can't prevent people from exploiting the system, but you can gain loyal customers by just concentrating on showing goodwill and pleasing the honest people instead. Withdrawing your "trust" from all for what only a (predictable) part did wasn't really trust in the first place, and doesn't earn these publishers trust from loyal customers either.

Because random people pop up from time to time, snarling about how their FREE, GIFTED game, is redeemable only on GOG and not on Steam... Imagine what a ruckus they would make, should they have to PAY for that game, too...

CDPR can't be too cautious, nowadays... Even gifts of theirs make people receiving them angry, as it seems... Not CDPR's fault, as far as i am aware/concerned...

I don’t get what you’re talking about here, could you explain a bit more?

I remember having read this somewhere, too. As to where it was, I cannot say with any degree of certainty.

I think it would be good for GOG if you could buy GOG keys also outside. All GOG would have to do is provide a mechanism for it and increase the cut slightly in order to compensate for other losses.
I don't understand fully what you mean, but for the things I understand I don't think they are true.

Humble's just another a steam key reseller, the have the very occasional rm free giimmick to fool people into buying from them. Why would GOG want to be associated with that, we would just have a forum full up with "I brought XYZ on HUmble and can't play on Galaxy" threads.

Because the HIB is a competitor to GOG, while HIB is just a reseller for the other platforms. If GOG wanted to make a bundle it would make it here and not post it on there.

It actually seem that most GOG bundled keys are from Groupees.

I think amok was referring to people who gave away their Steam key or traded it in for something else, while keeping the DRM-free download for themselves, acting as if they had bought two copies of the games in question with one purchase, when the system was meant to provide both Steam key and DRM-free download only for your own personal use, not to share with others.

It should also be noted that there's a widespread belief that it's impossible to distribute GOG keys through Humble.

Not too long ago some Kickstarter project (was it Armikrog, or something else?) said that it's not possible for backers to get GOG keys because keys are distributed through Humble. Only after some backers pointed out that Broken Age managed to do that, they started to look into it - and eventually managed to get the keys to backers.

Now it's not the same thing as bundles, but I think there may be a common factor. GOG, and the way GOG works, is not that well-known among publishers. In fact, I have seen it happening a couple of times that people ask publishers whether Game X is going to be on GOG, and the response is something along the lines of "I don't know GOG, but will look into it".

The problem here is wider, as Leroux says - people keep one (DRM free) copy and give away a key, thereby multiplying the licenses. (I could go more into the legal area of games licenses and service keys, but maybe not now - just enough to know they are not the same. A service key ≠ game license).

When you buy a bundle you buy one single license for each game - not multiple licenses. Ergo, you can not legally keep the DRM free copy and give away the Steam (or gOg, or Desura etc) version at the same time.

The trust given to the buyer is that they would not abuse this system. However, over the years, you keep seeing the give-away and trades (not only here, but in all gaming communities) where this do happen. Ergo - the trust given by the bundle buyers have not been given back, and it is not surprising that the developers participating in the bundles do not want to continue with this practice.

Granted, not everyone do this, and it may be a case of the few ruining it for the many, but I predicted this would be more and more the case a few years back due to this (and got a lot of flack for it in the process :))

Well, you probably already understood that I’ve been "guilty" of this myself ;)

Not having a Steam account, I thought it was nicer to give the keys rather than letting them rot on my virtual shelf. (I never traded/sold any Steam key however, only giving them away for free)
In my defence I always give (much) more than the average price for bundles, and actually despise those who takes all of these Humble Indie Bundle for 1$ each.

Seeing that Humble does not seem to discourage in any way the gifting of Steam keys while keeping the DRM-free installer, I never thought it would be seen as bad practice. But your reasoning makes perfect senses.

For the record, I despise those who despise $1 private-use bundle buyers. If a game is sold for $1, or for that matter given away -- like e.g. CItizen Kabuto right now on GOG -- it means the rightsholders have decided to sell it for $1 (or give away for free). Unless something unethical is happening behind the scenes (like, rightsholders trying to cheat contractors out of royalties), then it's okay to get the game.

(And if the rightholder is in fact trying to cheat a contractor out of royalties, it's better to abstain from buying altogether and maybe donate to the contractor's legal fund.)
