PayPal did their due diligence and then unfroze the account. Completely normal.
Sorry, no, it’s not “completely normal” to freeze an account for weeks without any recourse or communication and then be like “all good I guess”.
You could easily break a company doing just that. It really fucking sucks and should never happen.
Also, this isn’t even compatible with copyright law in some countries. I.e here you can’t give up authorship at all; you can only grant an irrevocable, perpetual license (that might even prohibit you from distribution yourself and such) but you’ll always be able to say “I made this” no matter what their license says.
