I disagree on telegram. It’s never been more relevant. Both Russian and Ukrainians post on them real time involving the war. You could follow the failed coup on Wagner via telegram.

That's because of the user base, no other reason. And you could follow not that much.

Conceptually, I think there’s a huge need for a telegram like service that’s more or less free for all parties to broadcast via channels. Obviously there are downsides, but I’d argue the ability to broadcast revolutions real time is worth it.

We are on one of such services now, FFS.

The problem is telegram itself isn’t really trustworthy given the Russia connection

You don't have to think that far to say it's not trustworthy. Just read about its protocol and how its creators are as people.
