Thank you for the replies, so I'm not alone in not liking this
I did not reply either, but I didn't realize I could still use the site without this
Maybe they will just use it to manage copyright on works that are not expired in all countries? I wouldn't mind that I guess, what I would mind is if some editor decides that they don't want to sell in a specific country, or only through a specific channel. A bit like Amazon refusing to sell me ebooks because I didn't buy their reader
