But those parts could be used for anything. There is nothing about buying electrical components that transfers a license to listen to the radio.

Technically, the user had to buy their phone too. That doesn't convey any special powers to the user to see/view CBC videos. (if any were needed)

I think you've misunderstood. Someone said that the issue is due to the app author charging for the app. Someone else said that even a radio isn't free, since you have to pay for that.

This has nothing to do with licenses.
