Almost literally every single social media site in the past ~15+ years has had those exact terms in it.

Everything you upload, almost everywhere, can be used by the site owners to do whatever they like for their own purposes (reselling is somewhat often excluded / non-transferrable). There are a handful of exceptions, but they're very much exceptions, not the normal rule.

I cancelled my Instagram account when they added those terms in the early 2010s. At the time it was mostly photographers reading them and closing accounts but it wasn’t exactly a secret.

Speak for yourself.

“Few”, maybe.
