A good first step. FOSS projects have GOT to stop using Discord as their primary engagement and documentation method.

Privacy is not necessarily anonymity. Signal uses a phone number to prevent spam and DDOS attacks on their network. Session doesn't do this and got wrecked by DDOS attacks to the point where most of the major groups are pretty much dead.
Use Signal to talk to people you know. That's what it's for. You don't use it for anonymous chats.
That could be what they're waiting for.
However, I do not believe SteamOS is going to be the silver bullet people think it is. I'm somewhat of a fanboy of Valve but SteamOS is really only good for a console-like PC experience.
People who want to ditch Windows need to look at Linux as a whole, not just SteamOS.

I love them if they're done right. Bethesda and CDPR do it right every time. I do really enjoy Ubisoft's open worlds back in the day, such as the old AC games (Rogue and before), Watch Dogs games, etc. Of course, RDR2 is also a masterpiece in this design. You mentioned Days Gone and I enjoy that one too, it's designed in a way that doesn't feel exhaustive.
Problem is, because of the scope of the games, it tends to take too much time. If the devs don't make the exploration and side activities fun and worthwhile, it's easy to lose steam and get burned out.
I do find some of them great for killing time, though. I'll sometimes load up Watch Dogs 2 and free roam, do multiplayer activities, hunt down collectibles as I listen to cybersecurity podcasts. Same with RDR2 if I'm listening to podcasts about America or traditionalism.
I personally see Peertube as something that'd be better as a small-scale, reasonably low-key way of storing and sharing videos if you're not interested in monetization or views. For example, documentation for a passion project.
For everything else, a different form of decentralization makes more sense, such as Odysee (though we'll see how the Arweave migration goes).
At this point, I actively encourage people to boycott this thing. Steam Deck is better anyways.
