Wireless Data

You wouldn't keep them all from going under just as we didn't keep all the airlines form going under or all the car manufacturers from going under. You let consumers decide what they want in a phone and the companies that figure out how to do that and make a profit are the ones that stay in business.
Here's the thing, in the USA consumers have almost no say as to what functionality gets put in a phone the decisions are made by the carriers and then we have to pick from what they sell. This goes against capitalism, just like the airline, railroad and energy industries some will fall by the wayside when subsidies are removed but people want phones so some will survive and eventually make a profit.
