Sorry, I'm still confused what you mean by "be prepared before it happened". Are you saying they should have pursued a different strategy/loophole around copyright law? That they should have realized they had no chance and not pursued funding? I'm not trying to be argumentative, I just genuinely don't understand what preparation you're saying they should have taken.
For the record, I work at a company with a lot of former Navic Networks employees (the company Chet Kanjoia founded before Aereo) so there's plenty of talk about Aereo and I'm pretty familiar with their model.
I can't imagine myself at their position so all I can give my honest opinion not judgement. What I am saying is that they should have suspected that. It is not my fully informed opinion and it can't be. And I can fully understand your point too. That's pretty much it.
