If this was more like Youtube Red, I'd be all over this. I would love to pay to remove all google ads. I get that uBlock exists, but I want to support the sites I use.
Unrelated: the sidenav thing is empty? WTF?
The content creator would just like the money. They don't actually want to display the ads. If they could get the money without displaying the ads, they'd be over the moon.
Why doesn't Google make it work across all sites, and pay the sites using Google Ads the average revenue they were already getting per page view?
The problem is that - as described above - many websites use ads from multiple networks, so actually even if you paid, most ads did not disappear. It was more or less random. Also, it turns out ads make sites a lot of money (who knew), so to get even that sketchy coverage required you to pay a LOT.
Online advertising reminds me of airline travel in the sense that people complain about the low quality service but are only willing to purchase the cheapest flights. The industry has shifted to accomodate what people actually want, not what they say they want.
