I tried to be the good guy on mobile and put up with ads for years. But I recently installed uBlock because I almost couldn't even read the content anymore.
Agreed. Erstwhile ad-free websites like BBC News for example now have an annoying full-page ad on mobile with a requisite tiny "Close" button. The worst part is, the news article loads before the ad, so you can see the article text and image for ~1 second before the screen flashes white and the full-page ad loads. That's a fail on so many levels, it's far simpler to view the site on on Firefox Android with Ublock Origin enabled.
BTW I have the BBC news site whitelisted on desktop because the ads are not nearly as intrusive and UX-breaking.
The breaking point for me was a neverending barrage of autoplaying, unstoppable video while on the subway. Now it's not just intruding on my own patience, it's pretty rude to everyone around me and I can't make it stop.
