Most major sites like Reddit, Yea Forums, Tumblr, Twitter, etc do have underlying cultures that differentiate them, but you're right that they're mostly the same, largely because the userbase has a lot of the same people. I can shit on Twitter all I like but I still have an account to follow artists.
Yea Forums just isn't some "underground" website anymore, it hasn't been for a decade. In fact ironically, it went from epic /i/nvasion raiders to a common raiding target for discords and smaller outside websites.

Because the normalfags have found Yea Forums, this is no longer the niche edge of the internet. You can unironically make a "trannies good" thread and get praise for it

WHICH IS IT

It's always been normie outside of Yea Forums's antics at one time with all of the cp that was being posted openly. Then because of that the sites traffic blew up because people wanted to see it for themselves, not the cp, but the forum as a whole.
