It's anti-competitive to app devs, not other wireless providers. Classic "pull the ladder up behind me" behavior.
I'm expressly talking about the app devs. It might be truly anti-competitive "ladder-up-behind-you" if all app devs were forced to sponsor client-side traffic. Think of taxi tokens- a fixed barrier to entry. But even then, to be an anti-competitive barrier to entry it must also be high . The cost of a postage stamp on your government paperwork is a barrier to entry, but it is not anti-competitive.
I think this kind of stuff is highly regressive. The Internet was this place where you succeeded on your own merit and not because you pay-to-win. A place where a tiny company like Google was able to sell their service because it was on the same playing field as lycos/yahoo/altavista. If accessing Google cost you money while lycos/yahoo/altavista were free, nobody would have ever tried Google. And without enough people searching and clicking on links there will never be enough seed data for a good ranking algorithm to work.
