That doesn't include all of the transcoding and alternate formats stored, either.
People signing up to YouTube agree to Google's ToS.
Google doesn't even say they'll keep your videos. They reserve the right to delete them, transcode them, degrade them, use them in AI training, etc.
It's a free service.
It is bad enough we can deepfake anyone. If we also pretend it was uploaded by you the sky is the limit.
Since you didnt ask, let me needlessly elaborate.
You can have YouTube or X or Facebook "design" a web page for you but those are always extremely lame. Just have websites in stead?? Their moderation looks more like a zombie shooter. Wikipedia has some kind of internet trial but that is so unsophisticated that it might even be worse.
It could be a simple redaction with a number of seats that can be emptied when the users request it though a random selection of jurors.
The redaction makes suggestions and eventually removes your website.
The site can still be publicly available before and after, it just doesnt live in the index.
