Of course they do. Every invasive thing I'm made aware of, will be blocked.
My home network runs Pi-Hole, and every browser has uBlock Origin. The Internet has been a bearable place. And then I happened to show my 2 year old a cartoon from Youtube on a non-adblocked device.
My. Freaking. God.
It's full of ads.
The cartoon is 10 minutes. Every minute, an 15-second, at the very least, ad rolls in. Like fucking gnats by the river in the summer: you get one, two, and then you are swarmed in them. There weren't the yellow markers anywhere on the progress slider, too.
Not all of those ads were good for kids, too. One was, I kid you not, an ad for Jira. An ad for the fucking Jira, in the middle of a cartoon. Won't anybody think of the children!?
My daughter was very much not impressed. So was I.
I promptly got uBlock Origin running, and youtube-dl'd the whole channel those cartoons were in, for good measure.
