I can easily afford that but I never want to pay a single penny to Google/Alphabet Inc. More of an ideological thing than economical, probably many have different reasons here instead of not being able to afford it.

Also, "then don't use" is not an option either as almost all the content out there is uploaded to YouTube, so it isn't like same content is available on Vimeo/Facebook etc.

Without trying to sound too puritanical, your stance sounds like a way to avoid paying creators

Nope, seriously. If there were a way to directly pay the good content creators (not talking about $5, Patreon etc, but having a microtransaction everytime I watch a nice video like 0.05 each which does sum up to something similar aggregated) I'd love to.

If you pay a company built around ad revenue to remove ads in one particular product, you now have a big flag “has money and willing to pay” on your profile.

No ads on that product, sure, but very much not coincidentally you cannot opt out of all ads across Alphabet, and the flag is a very strong signal for elsewhere you will be shown ads (even if it’s not made directly available to advertisers in targeting settings).

Google had the whole 'you can outbid advertisers if you want' feature but killed it: https://en.wikipedia.org/wiki/Google_Contributor
