well, the Big 4 networks don't care about OTA signals being free, they want to make their money by holding pay TV providers hostage with expensive and outrageous demand for retransmission and ad revenue. they don't make money on this and i'm surprised they haven't started the trend of phasing OTA out in favor of getting more money for streaming their content and what's left of paid TV providers in the dying cable/satellite industry>
while yes, Locast did open pandora's box in the form of stealing live OTA signals and committing "copyright infringement" and possibly violating the "DCMA" laws. but at the same time, people are asking, why are people paying for something you get for free as these OTA signals are free, and in the case of Locast, they are giving those with good internet and poor TV signal reception or no antenna at all and can't afford to get one or afford to pay for both internet and paid TV at the same time. the networks are mad cause they are trying to find a way to stream and make money out of it, CBS and Disney are they only ones streaming that would put their stream of local channels behind a paywall with CBS's CBS All Access and Disney has Hulu with Live TV for live ABC streaming. i'm sure when NBCUniversal/Comcast launches the new yet to be titled NBCUniversal streaming service they will put stream of NBC stations behind a paywall, and i wouldn't be surprise if Fox gets in on this by launching a new paywall tier version of their "Fox Now" app with the live stream of Fox bundled with their Fox Sports channels, Fox News Channel, and Fox Business Channel.
