I can give you a more concrete example — quote-boosts.
One of the first culture clashes I recall regarding it was when Black-Twitter tried to move the the Fediverse.
A lot of people who were part of Black-Twitter were used to quote-boosts. They had a culture war with a very, very, very small fraction of (less-than 0.002%) of the Fediverse.
(Most of Black-Twitter seemed to leave the Fediverse and form BlackSky.)
Also ...
Misskey (and its forks) and Akkoma/Pleroma (and its forks) have had quote-boosts for years. (Much before Mastodon.)
Much later, Mastodon adds quote-boosts. But makes them work differently. Makes them permissioned.
(Misskey, Akkoma/Pleroma, and forks quote-boosts are NOT permissioned.)
That causes a different mass-culture.
If you have a fediverse account, you can quote this note from your own instance. Search https://mastodon.social/users/reiver/statuses/116093407132316096 on your instance and quote it. (Note that quoting is not supported in Mastodon.)
