Like, platforms don’t actually own your data and usually explicitly state so; if for no reason other than not having liability for what you post.
If they did actually own the data (beyond having the very broad license to use it) they’d also have to curate 100% of it, otherwise they’d get sued to oblivion by copyright holders and whatnot.
Ehh it’s not that simple either way.
