1. A lot of people seem to like video ads. Movie ads specially tell you 'whats hot', and general ads put you 'in the loop' so to speak. I've tried to install ABV for a couple of people who won't let me because they actually like ads (as in youtube, not the shiny bright popups). This may be true for more people than HN crowd would assume.
2. One of the biggest problems I have with non-cable is that I need to think. When I'm with friends, we spend a very considerable amount of time trying to agree on what we want to watch, and often end up watching some stupid cute cat video because we couldn't decide. TV solves that. Perhaps if cable were referred to as 'a curated platform of best video content, being streaming 24/7', the conception would change?
