Adding onto that, there’s a browser that does that.
It is, in fact not a scam.
Ever heard of “Brave” browser? They compensate you for watching their ads. I already made the modest sum of $0.1, and each day make about $0.01-0.02 if I’m lucky.
This isn’t bad considering it impedes very little on my experience.
Salad doing something like them would be epic, but it involves some issues, like company finding and then the integration of it in many browsers.
I don’t know the extent to which something like an extension can change the browser, so I can’t tell if it really a difficulty or not.
