That falls under the server argument still. The ToS is essentially the item that caused him to be bumped up to business class. Anything in the household is covered - you don't order internet lines per household user. Anyone outside the household connecting to equipment in his house implies serving which hits his ToS. Unlimited still means unlimited to Verizon. If he was using 77TB and no one was connecting to his stuff (not sure how he would accomplish that much bandwidth without serving), there would be no issue from what I read.

The issue wasn't his data consumption but rather that he was hosting servers. Unlimited still meant unlimited in this case. Just an issue of home vs business models where no hosting vs hosting is available in the ToS.

It might not have the same manufacturer enforced DRM but Sony's wording implied it could be publisher enforced. Doesn't sound like a slam dunk win for Sony. I think both will end up with DRM in the coming generation.
