Relatively few? Those services are available for people who want to pay for them.
Personally, I use Gmail, Facebook, and a litany of other free services. I'm fine with the exchange.
Are you accusing me of not being mature enough to make this decision?
So, yes the current model is cheaper for me. Still, I would prefer a world where you pay for what you use without all the tracking and adtech. Selling a lot of useless crap just ruins the planet and makes our life worse in the long term.
Ad blocker is never about blocking the ads themselves since five years ago or so. Since then, the point is always to block tracker and fingerprinter scripts in the ads (sometimes these scripts are almost malicious [0]) to reduce the information collected by advertisers (and abusers of the ads system) while browsing the web. I actually miss the plain old banner ads without shenanigans, they need to come back.
Of course, once a considerable mass of people started using the internet, these 'plain' browser ads started taking up more screen space than the content itself.
Thankfully Carbon Ads seem to be pretty friendly and non-intrusive (only an image with text is allowed, and I don't think I've seen any GIFs) so I have them whitelisted in UBO.
You have that available to you! You can pay for Protonmail or a variety of other email services.
Facebook is a more interesting case, because what you're really asking is for your friends to make the decision to pay instead of be advertised to. They get to have a choice, no? I always feel a little creeped out by sentences that start with "I would prefer a world where..." and end with, basically, everyone does what I want.
A lot of people seem to think caveat emptor is good for society, but clearly it is consumer hostile.
