I believe it's actually called predatory pricing & is covered under antitrust. But it's not that easy to prove. It is also a regulatory practice to keep the market competitive. Additionally offering two tiers may seem easy but you risk pissing off a potentially large portion of your customer base & the ISP who's name your sullying in the public space. It takes some balls to go out and say "AT&T are being dicks so you have pay more", some companies will not do that & would rather do some backroom deal that negotiates a lower rate than the sticker price AT&T is asking. The result is still that AT&T get's more money in the end.
