There's a law of conservation of advertisement. It's not like you were going to get away from ads forever when switching from real TV. I prefer the purely interstitial (untargeted) commercials from real TV. With a DVR I can fast forward them, or always at least mute. Having Amazon/Netflix "recommend" things to me through what should be a functional unbiased system is more insidious.
If it's for free OTA television, I'm OK with that. I don't know why people never rose up against it in cable/satellite-only channels that they pay for.
/I'm OTA, Netflix, and the library. But I mostly only use Netflix for the DVD service. I'm fortunate enough to have enough going on in my life that I watch very little video.
