Nobody is expecting encyclopedic depth. Just some consistency. There’s a big functional gap between “kill your TV, get a life” and “I’m watching a movie on my TV right now”. There’s actually plenty of folks on FR that throw around the “kill your TV” line that at least claim to not own one at all, not even for watching classic movies on DVD. So it’s not really an “obvious sensible limit” to think the guy that says “kill your TV” didn’t kill his.
To most, “kill your TV” means “drop the continuous-feed ad-driven content defined by others (akin to a magazine subscription)”, which is different from “watch what you want when you want without ads (akin to reading a book)”.
Sorry if you were unaware of the nuances of a common social code-phrase.
