As far as I can tell, this fight seems to be between two ways to watch a sports game:
1. on over-the-air broadcast, which is free to receive. 2. cable television, which is not free to receive.
Apparently Aereo makes (1) easier, which presumably means more people will choose (1) instead of (2).
What I don't understand: * If I could watch the sports game for free, why would I ever choose to pay for it instead? * If they (I think in this fight 'they' refers to the NFL and MLB) don't want me to watch the sports game for free, then why do they allow/provide free broadcasts in the first place?
From what I can tell, the whole sports game watching market looks even more ludicrous than the arbitrary restrictions online TV/ebook market (the number of books in the kindle store that are available - then suddenly disappear when I log into my Australian amazon account - presumably publishers/authors love losing money).
