B1tF1ghter: Your argument is void since product page was clearly live for few hours before the "many gamers" happened.
https://web.archive.org/web/20201216100054/https://www.gog.com/game/devotion It's especially void since you used that argument to compare GOG to Steam - which is hilarious - since in THIS CASE Steam actually had it for sale for around 6 days - and in Steam case it was brought down by developers themsevles and NOT Valve - so Steam case is nowhere near comparable.
edit:
Ladies and gentleman I found another flaw (cringe) in this ancient forum software of GOG. Apparently it refuses to properly parse webarchive link and behaves like there is nothing before last " https ".
Ergo, you have to manually copy paste the link I posted as otherwise it directs stright to GOG and not webarchive (enirely fault of forum software used here).
wolfsite: This has been posted before but Steam has been accused of blocking games for political reasons

and they have remained quiet just as GOG has.
There is a differene between shaky-ground accusation and a fact.
As well as "refused to list it at all and didn't make public statement" (which btw, any store can, and since stores different than Steam ususally don't accept "just about everything" you just don't get to hear about it most of the time in other stores, like, you never officially know what for example Origin refuses and such, I'm not saying it's good that Steam refuses, but they also have specific content guidlances and if a game is going too far they can just refuse it, also without having access to official Valve reason stated to developer it's still just speculation) and "signed a distribution deal, made product page live and pulled out few hours later stating no-proof highly questionable reason".
I have read some articles on your linked Valve case and so far I have not seen a solid evidence or even hint that that could be DEFINITELY due to "censorship" or anything close to it.
All these articles basically go by "we made yet another controversial game, got rejected on one of distribution platforms and we got upset so we decided to publicize it without providing details so people can speculate and publicly shame Valve while our games get free publicity".
If developers bring it to the public while refusing to give exact quotation it's basically biased fearmongering and it's hard not to see it as a form of "let's make it controversial so it gets viral and our games get promoted for completely free".
If there would be legitimate concern why not just publicize quoted proofs? Think about it.
Valve blocks a lot of games for a lot of reasons. 99% of the time nobody but the developers and perhaps small community interested knows about it.
Also I would like to point out that Valve didn't make a statement. And apparently both developers refuse to directly quote Valve reasoning provided to them - it's almost like developers could shame themselves by proving their games violated some existing policy - of course without knowing the Valve reasoning this couldn't be proven, but so couldn't be "censorship".
Meanwhile GOG made one of the greatest "hold my beer" bad moves while being carefully watched and with evidence being collected.
The Steam behaviour just cannot be compared to GOG's case at all.
fronzelneekburm: The best part is that the game page shows that the devs put enough effort into this release they even enabled Galaxy achievements.
I sure hope gog compensated them ROYALLY for all this wasted effort.
Everything about this miserable affair pisses me off so much I can't really find the proper words for it...
Considering that you cannot put a product page live nor announce a planned release (especially just few days before planned release) without signing distribution contact before first GOG should be held legally responsible for this whole ordeal by developers / publisher.
