Bluesky in particular has this problem because it inherited a kind of leftist crustpunk poster from 2016 Twitter. They had a weird affect where they hated "nerds" for some reason and pretended to be those jock bully characters from 80s high school movies.
The modern Bluesky form has evolved into being terrified of "AI" and screaming at anyone who uses it or has ever heard of it that it doesn't work and will never work but is also using up all the water and steals everyone's art and is going to make everyone unemployed and also you're a STEMlord who needs to take humanities classes to learn to be ethical.
They're currently working on inventing new slurs for AI chatbots which are mostly remarkably offensive.
