I'd like to give GOG the benefit of the doubt. We still don't know if he was fired over this, he decided to step down or he's just taking some time off. There's no communication from either party, which is both disappointing and annoying, because all it leads to is negative speculation.
That being said, if he was indeed let go (either by force or by suggestion), then this is certainly a decision I cannot get behind, no matter how much I love GOG. The entire reason I like this website is that they cater to gamers. "GOG puts gamers first", is what I said about this place. But, again, if this is true, then this would be no longer the case.
It's a sad trend in the last few years, but companies for some reason prefer to listen to complainers with a loud voice rather than their loyal customers and fans. People who'll never be happy because complaining is all they like, and don't really have the power they pretend. In trying to make them happy (which, again, is not possible), companies end up making their fanbase unhappy, which ends up costing them more.
So it could be that GOG did not proceed in this fashion, but it is certainly the impression they're giving. Again, some communication would go a long way.
