There were no copyright issues here, only trademark / impersonation. Those rules are extremely fuzzy, and the usual method of mentioning a trademark you don't own, practiced even by mega-corporations, is by attaching a disclaimer that it's not their trademark.
Except Google clearly told him that his actions violated the rules. This isn't even a trademark issue. There has been no legal action taken against him. This is a rules issue, and the sole arbiter of those rules told him he was breaking them, twice, before banning him. Can you blame Google for banning him? If he didn't get the message after the first two warnings, why would you expect him to get it after the 20th.
