Regulation is not socialism however when government starts dictating how and what a businesses charges for simply because customers don't wish to pay the market price for those goods and services you are walking on a slippery slope.
With over regulation there is a fine line between capitalism and socialism.
Carriers are not simply charging for data with no benefits to the consumer, they charge for data and require it and as a result, pda prices have come down, data prices have come down, and data speeds and coverage has improved. By requiring everyone with a pda to pay for data regardless of whether or not they use it helps spread the total cost of ownership for everyone, the consumer and the carrier.
Lastly, capitalism only works when the consumers exercises their rights, which is to buy or not to buy. If consumers stop paying for such things then the market will auto correct itself.
