Random semi-crazy thought that just might work:

Musk/X isn't using the trademarked words "Tweet" or "Retweet" anymore. In fact, after the rename, any references to these words have been completely scrubbed from the site. The trademark is as good as abandoned.

So... could we, collectively, just start using "tweet" and "retweet" as generic words for "microblog post" and "boost", respectively, regardless of platform? Doesn't matter whether they're from the Fediverse, Bluesky, X, Threads, etc., they're all tweets. Lowercase, of course. It fits the way the term has been used in popular culture for years, instead of letting Musk just erase that.
