Organisations use things like Twitter to broadcast news as push notifications to a large audience of subscribers. This is something that they're going to want to keep doing, and is only one aspect of social media. On its own, I don't see this ability as being damaging. They're basically just using Twitter as a more efficient mailing list. Things only get bad when opaque AIs start ranking shit and publishing to non-subscribers.
ActivityPub does provide a really good way to reproduce this ability. It is a good solution.
Bluesky is just another Twitter, subject to all of the same drawbacks. The only difference between the two of them is four years.
Ah yes that's it. Steal the oil, sell it, and use the proceeds to pay the crew to sabotage Russia and its allies.
