looks like rendering adblockers extensions obsolete with manifest-v3 was not enough so now they try to implement DRM into the browser giving the ability to any website to refuse traffic to you if you don't run a complaint browser ( cough...firefox )
here is an article in hacker news since i'm sure they can explain this to you better than i.
and also some github docs
If you aren't native English speaker and therefore use a different keyboard layout than US, pretty much all features disappear on iOS. The keyboard is garbage compared to Android's native keyboard and for some reason even after 3 years of iPhone ownership I still write more typos on the iPhone than I ever did on Android phones.
I wish I could use some 3rd party keyboard, but because Jobs decided in the past that Apple's keyboard is the only thing users ever really need, I can't. There is a limited support for custom keyboards but in practice the user experience is garbage.
