You don’t need to track people to pay for things with ads. You can advertise based on the surrounding content pretty effectively. It’s what TV channels have done for years.

Behavior ads or paywall is a false dichotomy.

And news papers. And a long time ago, that's how Google ads worked too.

Contextually relevant, non-intrusive, respectfully done untargeted advertising is acceptable. Quoting myself from earlier times: https://bostik.iki.fi/aivoituksia/random/no-stalking.html

I want to consume content that was made by people who simply want to make that content for the sake of sharing information.

I don’t care if content that is made by people that only make content to make money is pay walled. They can have their 10:01 long YouTube videos and recipes with a preamble of their life story behind a paywall. Sounds good to me.

I want to see what business models people come up with without ads sucking up all the oxygen in the room. We tried ad supported content, it was bad, let’s roll the dice again and see what we get.
