The advertisers already paid for content to be distributed. The broadcasters aren't even missing out on theoretical revenue cause no subscriber pays for over the air tv. If anything they could increase ad revenue claiming more viewers.
I'm missing something... Cause I don't see why broadcasters are against Aero at all. Is it cause cable companies pay broadcasters for content and people think Areo will cut into that?
You're missing that broadcasters transmit to a select geographical location, so they can still sell the transmission to cable and satellite networks. By making it cheaper to watch those channels outside of the areas covered by OTA broadcasts, they're making it easier for current cable subscribers to "cut the cord".
Aereo makes new users sign up with a credit card linked to a zip code within the OTA broadcast range of the metros that they operate in. The users then get the channels that are available in that area. See https://www.aereo.com/channels
Theoretically Aereo makes it more expensive to watch these channels(but easier and more reliable) than a one time purchase of your own antenna.
If Aereo were ruled legal today, the cable companies would figure out tomorrow how to duplicate Aereo's position and avoid paying the broadcasters any fees.
By statute, broadcasters can choose whether a) local cable companies are required to carry their networks [which is why public access still exists], or b) to negotiate for the rate, which lets the cable company walk away if they cannot come to terms.
