Some organizations only post information on Twitter, especially those with limited resources. And if their followers are themselves limited in number, then that information is not disseminated.
For example, the Dutch Air Force is currently posting updates on their ongoing airborne exercise exclusively on Twitter: https://www.defensie.nl/onderwerpen/f/falcon-leap

Why does anybody (that’s not some right wing, white Christian nationalist nut job) still use twitter?
Because not everybody thinks the same as you?
People are entitled to their own opinions, just because you think something is wrong doesnt make it objectively wrong.
On Bluesky/ATProto, I am free to chose my own algorithm or my own client software and affiliate with the people I want to. My data is always my own because I can host it on my own PDS. On Mastodon, I have similar freedoms, and you can opt into bridging ATProto with ActivityPub through Bridgy Fed. I like the freedom of the open web, but I guess not everybody thinks the same as me.
