If every person who writes them is in a hostile angry rage filled with hate and outrage and that's the only feedback they ever receive, I'd suspect they would not bother considering distribution on GOG. I imagine they (or any company) considering distributing a game on any particular distribution platform is going to want to not only see that there is a market for their game on that platform but also have a two-way positive relationship with the fans of their games. If all a company hears is hatred anger and vitriol, that simply much more likely to keep them away. I can't see how it could make a company super eager to prioritize it anyway.
Someone once said something to the effect ... "you get further with honey than you do with guns..." It's true more often than not and I think situations like this are examples where it is more likely the case.
If however they hear positive encouraging messages from fans of the games politely telling them how much they'd like the games to be on GOG.com, and perhaps even some of their other games, then they receive a positive message and experience, and there is power in numbers. If enough influx of positive requests of such nature happens, a company is much more likely to look at it as something to contemplate and possibly consider in the future than receiving a tonne of hatemail.
I could of course be completely wrong though. I have more positive experiences getting what I want from people, companies, etc. via civil communication than via anger and rage and emotionally charged mud flinging though so I probably don't have the best data on what is possible to achieve by yelling and screaming at companies and seeing if they respond by doing what I'd like them to do either. I could have been doing it wrong all along!
