While it may not be different in a technical sense, I'd submit it's different in spirit. When one brokers AA miles, he or she knows that's running afoul of AA terms, even if they don't know precisely what they are. In this case, I know many people who ordered phones who didn't know that buying them in the manner they did was a violation of the terms. I certainly did not, and I would have never done it had I known. Sure, one is charged with knowing the T&C's they agree to, but in all reality, it's just not a practical expectation.
Please blame this on the phone brokers. I had a dozen brokers reach out to me for iPhone resales and eventually turned them all down a few years in a row, losing a ton of cash each time, all for the reason that I read Apple T&C and saw it was prohibited and when done on such a mass scale even if they didn't do anything before they might and are entitled to make an exception if the wanted to.
I would go one step further and say you can't look at google punishing you for breaking the T&C, sure banning someone from Gmail a little crazy for breaking the T&C of buying phones, but imagine 1,000 people joining together and changing the entire distribution network of their top of the line phone.
For example they make ad money from people having these phones and using them in the US, all of this is taken into account for their profits from production etc. And people joining together and shipping them out of country goes against those predicted metrics.
I don't mean to put anyone here down, and I probably would do the same thing and buy knowing there are risks and I'd be beyond mortified if I lost my Gmail, but I wouldn't think I have a right to sue or that Google did something illegal.
I hope they reinstate the accounts soon.
