Nobody is "consuming" any "YouTube videos". I couldn't care less about YouTube. It is just an intermediary to content that I would enjoy if it was published on any other website. More often than not, YouTube gets in the way instead of helping, too: hiding notifications and new publications, exposing my favourite creators to abuse through comments, financially and legally abusing them themselves with crappy copyright practices (e.g. video taken down because someone DMCA'd based on static noise, or video demonetized because it is political or mentions a curse word, etc.), directing my attention away from them by their awful recommendations (recommendations which are horrid in and of themselves and provide even less value as days go by), and so on, and so on...
And then, it is not like paying and ad block are mutually exclusive. I do actually pay for YouTube because I don't want the ads on my living room TV, but I have many devices with many browsers and I don't want to log in on all of those. For example I have a Chromium profile dedicated to shopping, on which I deliberately don't log in to any Google or other services, because, among other reasons, if I did, all my YouTube recommendations would be product reviews. And then, many apps of YouTube are just plain unpleasant, so on my main phone I use NewPipe, despite being logged into YouTube as a paying premium user.
So, just because I don't want to log in on every device and browser combo, and prefer alternative apps, am I supposed to see the ads, which I pay to not see? Just because a website I couldn't care less about needs to make money off the backs of people whose work I like, all the while abusing them deeply and causing them to burn out?
And I am not even beginning about how godawful YouTube ads are. Not a decade ago YouTube was liberally allowing Musical.ly ads in which half naked underage girls were dancing suggestively and getting explicitly objectified on nearly every video. And now _most_ of these ads are scams, disgusting politics, more scams, get rich quick schemes, and other godawful things. At least on TV the ads don't threaten your mental health. Why would I support a business as filthy as this? Just for the privilege of _sometimes_ being spared from it.
