Fairly certain you actually did give away quite a few of your permissions when you create an account and/or post things online.

I don’t think Google needs permission to index these comments either.

A few, not all, and in fact I gave many of them away under very specific licenses, of which they have paid exactly zero mind too.

If I allow my friends into my home for a visit, does that mean I should shrug when I return home from holiday and find out they’ve helped themselves to its usage without my knowledge or permission to do so?
