I didn't use adblock on my phone until recently because until Brave came out, it was such a pain in the ass (root, vpn, etc). But eventually I couldn't take it anymore. I got regular reminders of how badly ads have ruined the modern web. Any small to midsize blog had a 1-in-4 chance of crashing the browser with fake "YOUR PHONE HAS A VIRUS" ads that pull you right out of what you were reading. Extremely irritating and it's no shock to me why Brave was conceptualised.
