I've been working to get more involved with, eg, mutual aid groups and other forms of local capacity and resiliency building over the last year - one thing that's stuck out to me is how many of these groups' public face is an Instagram site. That might not have been existential a couple years ago, but given what we're seeing now with, for instance, Paramount making a rival bid for Warner based solely on their coziness with the current administration, it doesn't feel like the corporate media ecosystem is going to be an even "squint and you can kind of pretend" neutral territory for organizing and information dissemination going forward.
For all that tools like PeerTube, Mastodon, etc are clunkier and more limited than things like YouTube, Bluesky, etc, I think that argument is increasingly going to be irrelevant to their value - we need to start ensuring our capacity to go from 0-1 on media distribution, not from 10-100 or 100+.
