Why, from first principles, should YouTube allow this? Why shouldn’t they go thermonuclear? I understand ads are annoying - I block as many as I can! - but I’ve never seen someone put together a coherent defense of the practice.
Regarding reciprocation, a lot of platforms offer a free tier and then offer additional features for paid subscribers. There's the principle of reciprocation at play: they give me something for free and that then makes me more likely to pay for additional features. But I'm only willing to pay for features, not to have an annoyance, like ads, removed. The conditions I'd have to agree to feel coerced ... like making an agreement with Darth Vader: "pray YouTube doesn't alter the deal further by now only blocking 50% of ads for a paid subscriber." What do I, as an end user, get out of this other than feeling hostile towards YouTube?
It's my computational device and my internet connection. I think there's a very complex argument to be made but this isn't the forum for it.
