Hosting video content must be insanely expensive so I have some amount of sympathy for YouTube. However, ads earn such a paltry amount that I can hardly fathom how anyone can put up with it.
The total amount of ad revenue between all sites is only like $12 per user per year. So IMO it is a net benefit to block all ads (save your sanity!) and simply pay the creators of content you like.
Even just one $5 Patreon sub is worth more than all ads I’m likely to see so I block everything I can and IMO my conscience is clear
