You're living in a fantasy bubble if you think anything in this comment is insightful or representative of the current state of Twitter.
The only thing that was in doubt during the various recent Twitter changes was how rapidly it would decline - people have underestimated network inertia, which is why Mastodon and now Bsky have failed to capture sufficient impressions to convince everyone they're the "next Twitter". Which ultimately brings people back to Twitter - noone is going to Twitter because Mastodon/Bsky don't work, they're coming back because with each migration they overestimate the finality & are disappointed.
Ultimately though, slow as Twitter's decline is, it is continuing to decline steadily & will inevitably cross the critical threshold where one can consider it first irrelevant (Facebook's currenly approaching this state, a process which has been slow), then eventually "defunct".
TL;DR: declines always take longer than everyone predicts, but ultimately still happen. Comebacks generally speaking don't.
