I'm working on that. The hardest one to cut out is Google Maps, which doesn't have an ad free option.

Anyway, the value they receive is incidental: if I like content, I'll tell my friends about it. Not all of my friends dislike ads. I "market" the content via word of mouth. The content markets the subscriptions. Or the ads. Either one.

If I stop watching the content entirely (due to it becoming harder to discover) then fewer of my friends know about it. So it's not quite as black and white as you want it to be. The "grifting" population helps content to spread to the paying population.
