The Moral Case for No Longer Engaging With Elon Musk’s X

You are mixing "talking about Twitter" with "being on Twitter". If nobody on Lemmy or Mastodon said a single word about Twitter ever again... it would still outnumber them by hundreds of millions users. I don't like it, but that's still how it is. But consequently, ragging on it is not going to recruit people who left for the Fediverse.

But if you mean making everyone on Twitter to shut up in general, well, easier said than done.
