In the ongoing saga of the Wolfire versus Valve lawsuit, which is continuing, we've been able to see a funny little look behind the curtain and Tim Sweeney was not happy with Valve.
I loathe Epic Store but I wish there was better competition to Steam. They definitely offer better cuts for devs but I think they still need to understand what makes Steam popular the way that it is. There's a huge social media aspect, proton, bigger picture with the controller support...
We are in a very delicate situation where Valve can do whatever they want. They can suddenly decide to start making steam worse for users, adding more ads than we already have and we won't be able to do anything, because in the end we don't really own anything we have there.
gog has always been so anal about linux though, that it kind of feels like a epic games to me. you can't have a platform ran on drm free games, and then when people want to play them on linux (the "drm free" platform), they ignore and alienate them.
