Lol the PC Gamer article the OP quoted got updated.
GOG suddenly pulls troubled horror game Devotion mere hours after its return was announced
That didn't take long.
Update: Earlier today, Red Candle Games announced that its horror game Devotion would be released on GOG. But now, according to a tweet from GOG itself, that is no longer the case.
This is a sudden (and baffling) decision. Who are these mysterious 'gamers' and what exactly did they say that provoked GOG to pull the game? We've reached out to the company for comment.
Well gone, gog! Real horrorshow!
Best way to wiggle yourselves out of this one is to go "Whoops, the intern posted false info! Calm your tits, everyone" and go ahead with the release on the 18th. If that means your site gets banned in China, so be it. Everyone there uses a VPN anyway, so it's not like a ban would close the market to gog altogether.
Because unlike what you may think, this isn't going to go away.
