I think you're kind of missing the point. Yes, the EULA allows this. A EULA should not allow a company to alter something they don't own in a manner that the owner does not want them to. Just saying "don't use it" is precisely why AT&T has the amount of power and influence they have. People like you don't understand that there are a ton of people who don't have a choice. "Just a piece of plastic" is not the issue and you and others completely miss that. It may be their network, but it's not their device. The more that you let AT&T dick around with peoples devices the more they will try and lock people down. I don't care who's service I'm using, they shouldn't have the ability to disable or alter a device to make it not work on another companies service without the customer having to change things out. AT&T are doing this because they are an unscrupulous company and they want to try and force people that don't know any better to stay on their piss poor and overpriced service. Since they are in collusion with Verizon to try and dominate all the cell phone connectivity in this country, and are willing to lie through their teeth to do so, anything like this should be instantly stopped. They should have NO ability to alter any device that they didn't sell you. It's not theirs to alter no matter how big or small the alteration is.
