It's just another gimmick to defraud people of their hard earned money. Air is free- now they want us to pay for that too.

Reminds me of how cable was suppose to be commercial free, since we paid a nominal charge. Now there's more commercials on cable than anywhere else.

Corporations, when left to their own desires, will find a way to nickel and dime the consumer into oblivion.

Oh, that's right, we're already there.
