I tried an iphone once about 6 years ago, but once I realized all browsers were essentially safari and there WAS NO ADBLOCKING, I was disgusted to emphatically go back to Android and Firefox with ublock plus. Apple is like the US government protecting pedophiles, but protecting adware and everything wrong with the internet, forcing people to be insecure and watch ads. I feel bad for apple users unable to use a clean ad-free internet.
iOS has had support for ad blockers since 2015. I never ever see ads on iOS Safari and have not for many years.
