> What's your issue with having to watch ads if you watch less than 1 hour of video content a month?
Moral issues, security issues, etc. These have been discussed in pretty much every thread about adblocking ever, really. I get that you might disagree with them, of course, but no need to rehash the here. I don't even like company logos displayed on my clothing, so you can guess which side of the "how much do you hate ads?" spectrum I'm on.
> There's a lot of content on YouTube that people upload that they have no intention of monetizing.
So on those you never see ads? Hilariously I don't actually know how Youtube works since the only time I've seen ads is when someone who doesn't use an adblocker shows me something (i.e., extremely rarely). Firefox + uBlock Origin (and Adblock Plus before that) has been enough to guard me for as long as I can remember.
> Why don't you or someone else try starting one?
Well, I can't speak for anyone else but I'm a middle-aged historian, so starting a video hosting platform is far beyond my expertise. Though in general asking someone "why don't you just go build it yourself" in response to a complaint about a service, software, or hardware item is a bit trite.
