There's a strange clause in the Dutch translation they offered me: at the end of article 10: [my rather literal translation back to English]:
If you [...] terminate the agreement, (i) you are not allowed to create a new Account and (ii) you cannot generate income with content in other Google products.
So don't cancel your account if you ever want to return - not even if you might want to return to anything they imagine in the future ... And art. 14 makes art. 10 permanent - even after you cancel the agreement.
