Powerful evidence it's not a broadband duopoly

The Washington Post's good article "Rewriting the Web for Mobile Phones" is powerful evidence that there is not a broadband duopoly in the U.S. The article explains that both Google and Yahoo are introducing programs specifically-designed for mobile phones, which by the way outnumber PCs in the U.S.

If broadband  access was a broadband duopoly, why would both Google and Yahoo be investing in moble phone Internet interfaces? And why does Microsoft have Mobile Windows on the popular Treo phones?

It doesn't sound like market failure to me. An analyst in the article said: "These are still the early days of the Mobile Web. Theres going to be a big, big market and there are some huge players that are gong to put a lot of resources into this area." (I ask why Snowe-Dorgan has no sunset provision for when there is more competition -- could it be that they never want it to sunset becuase the issue is not sufficient competition but protection from competition?

Yahoo in the article is making our case for us why one-size-fits all NN regulation is inappropriate for mobile phones (which by the way have not had NN since 1993.) Yahoo spokeswoman said: "With the mobile Web, we don't just try and plop PC-based services onto the phone. The network speeds are different, the device capabilities are different and the what consumers want from us is different."

If Yahoo understands how different Mobile broadband access is from landline broadband access, why does Yahoo support the rigid, one same NN rule for every broadband carrier regardless of their differences?  Could it be protection from competition?
