The underlying issue is that broadcasters are creating an artificial scarcity to drive demand. I find that to be more unethical than exploiting a loophole.
Which makes the whole "copyright" argument in this case even more specious, IMAO. You're broadcasting your content, for free, into the air, for anyone who cares to listen. What gives the broadcaster the right to dictate where someone has to be physically located in order to receive the broadcast?
scarcity of option to format change, timeshifts, rebroadcasting, and choice.
Broadcast tv (discounting DVR's) has set times for set programs, and i do not want that - it was only recently that recording broadcast TV was made legal in australia (can't recall how long ago off top of my head).
