content: They aren't thieves, but if T-Mobile doesn't like it, they shouldn't sell unlimited data plans. They should sell 50gb/month plans. But they REALLY like the advertising ability of that word "unlimited".  That is it exactly. And I am sorry, but the idea of "hiding tethering" is just bullshit. Even more so, is the idea that they think "only hackers" do this. Verizon has locked down Android phones for so long, that since my first droid, I had to root to tether. I had to root to get rid of their BS software too... In fact, I have never seen a droid phone that didn't need rooted to get a decent running phone. But that makes me a L33T H4CK3R in the eyes of T-Mobile.  As for torrents, I guess he doesn't realize that the phone makes for a perfect, low power seed / download device without being tethered. In fact, I do all of my torrenting (Linux mostly) directly on the phone for that reason (No, not seeding - just the downloading). Most interesting, is that they can tell you are tethering on the network no matter how you try to mask it. Because they have network reports set up to show them what sites you go to, protocols in use, etc. So if you are using it for Xbox Live (for example), it isn't like your phone is going to use those voice protocols on its own while connecting to those services.
