Of course you can't give up ability to use your name/trademark without making sure that it maintains it's integrity. Why is John surprised or find it remarkable

Of course you can't give up ability to use your name/trademark without making sure that it maintains it's integrity. Why is John surprised or find it remarkable? I'm surprised Google hasn't gone much further then they have. Looking at the crap AT&T is pulling with their "Android" phones must make Google disgusted but it's the price of free & open source. Trademark is the only point of control and I'm glad they are exercising their rights. Carriers almost never care about their users. At least with Google their interests are at least semi-aligned with making the users (me) like their experience with Android phones.
