So, in a nutshell, I guess what I'm suggesting is, you don't have to criticize GOG, but don't try to "block out" those who do.
If "blocking" means clicking the downvote button when one sees a message he doesn't agree with or a person he has personal vendetta with, I agree. For what it's worth, I feel those voting buttons, at least the downvote button, could be removed altogether. Currently they are misused, even by those who sometimes complain about them.
At the same time, it also seems that many of these people who complain "criticism towards GOG is not allowed in this forum, boohoo!" have double-standards, as they seem to complain about it whenever anyone disagrees with their criticism (ie. they don't like to see their criticism criticized, and whenever someone does, they complain that said person does not allow _ANY_ criticism towards GOG), and especially the ones who also complain that e.g. Steam should not be criticized here. Some even go to say that people in this forum should not defend GOG at all.
Just disagreeing with someone is not censorship.
I think it is natural that people who like a service hang around in its forums, and even defend the service in there if they _disagree_ with some criticism. For example, the big argument in the 5/10 thread was when certain someone was constanty blaming GOG of "bullshit PR", when at the same time he used the very same tactics claiming he trolls in these forums constantly just because he "cares" so much about the well-being of GOG. When you blame someone of something, first make sure you are not doing the same, ok?
The reason he (or anyone for that matter) doesn't want to see newer games in GOG is not because he is afraid of GOG going under, but because he personally doesn't want to buy new games from GOG. Yes, I am 130% certain his motives are purely selfish, just like for the most of us. For example, I want GOG to continue to promote DRM-free gaming (both on old and new games) simply because I prefer to buy DRM-free games. I don't try to sugar-coat it to bullshit PR like "I just worry that if GOG would start selling games with DRM, they would go bankcrupt... that's the reason why I oppose it, because We Care!".
It is silly for us mere users to even argue what is the best for GOG, as in "selling also newer games will destroy GOG as a company". I am confident GOG staff know the reality much better than us mere users, after all they are the ones who have all the relevant data. So I find it hilarious when someone acts as some kind of external expert who knows the best what is the best for GOG.
