some other thoughts: someone on here recently referred to the Mastodon migration as a good example of the whole dual power philosophy: setting up healthy, community-based alternatives to the current systems of power, ready to have people fall back to them (and all their benefits), when they're finally forced out of the current power structures.

I think building that out for Matrix, even if it doesn't completely replace all your communities (yet!) is something that is worth getting started with right now! It doesn't hurt to get yourself a Matrix account, after all, and you might find some community and discover you like it a lot! (I do! I wish my Discord communities lived there!)
