I consider myself lucky, the 5 people I followed all cross-post to Mastodon, so I no longer need Twitter. It may not be a viable competitor, we'll see, but in the meantime I get only posts from those people I follow. No recommended/ads/trending/sponsored/whatever cruft flooding over my feed, it's lovely.
I get that most people still need or enjoy Twitter and see value in it. And with 4-5 Firefox extensions it can be somewhat sanitized.
