At least pre-Musk Twitter quick to adopt popular user-innovations as first-class features (RT, QT, threads & more); features filtered upwards from users. Musk-Twitter is very top-down in trying to incentivize specific monetizable/political behaviors.
Haven't all this features been a thing since forever?
None of them were in the original product; they were essentially community-created.
As an example, RTs have been an official feature since late 2009 (https://blog.twitter.com/official/en_us/a/2009/retweet-limit...), more than three years after Twitter has first gone live.
To be fair, I don’t think I’ve seen much sign that Twitter understands what made Twitter great, either.
