#2 checking in. I pay almost zero attention to what Apple does. I'll pay attention if they start allowing Mozilla to ship add-ons with Firefox so I can run adblock on mobile like on Firefox!
#3 of a vast number: I don't pay attention to what Apple does, choose not to own any Apple products even though I do respect their technology, particularly Apple Silicon; would not have been aware of a launch of a new iPad if it weren't for this controversy.
You can run ad-blockers on iOS Safari (they're called "Content Blockers", I use Firefox Focus's) granted you're still stuck with Safari/WebKit for the time being.
