That's not up to you to say. If it solves the issues
I have with the modern web, it is an actual solution for me. And if changing my browser or installing extensions does nothing to solve the issues
I have with the modern web, then that's not even on the table.
A solution that works for a niche... works for that niche. It's not like your solution of switching your browser or installing extensions universally solves anything. I absolutely despise the user experience of Firefox (which you suggested elsewhere) and ads aren't even close to the top of the list of my issues with the modern web.
Once again, what annoys you may or may not annoy me and what annoys me may or may not annoy you.
