The de facto chat client used by gamers, often at the expense of platform-provided solutions, so I hope mods let this fly. Screen sharing of a game window is something that Discord figured out before anyone else, and it still might be the only one in town that works well for that use case. I'm about to start doing more research to see if any other programs can be subbed in, because this sucks. Wario64 facetiously linked a story about Discord getting hacked and revealing government IDs right underneath this story on Bluesky.
I'm expecting that if/when Discord does fall, people will just go to another corporate-owned platform that hasn't enshittified yet... but inevitably will. And the cycle will repeat.
This is what we're seeing with BlueSky. Sure, BlueSky pays lip service to federation in order to convince users they're totally different, but in reality they've set it up so that nearly everything goes through their master server and they hold control. I don't trust BlueSky any further than I can throw it, but ActivityPub is clearly losing the battle here.
