Very short version why I left Twitter

Elon Musk does weird and nonsensical changes to it.

Long version why I left Twitter

He is making the Platform worse for normal, non-paying users
Removing features that was previously free, requires now a Twitter Blue subscription
Twitter Blue aka "verification" disaster itself, creating exactly this "Lords and peasants"-system, aka it is more corrupted than before
The algorithm is pushing those, who are paying
Also the algorithm is pushing Elon Musk tweets by default (Cause he don't have enough reach by default, before these big brain changes, huh...)
