There are two, again two platforms that matter for phones. That's it. "Well, it is not 1, so we can just twiddle our thumbs and ignore the problem" is not at all convincing. And then people get sidetracked with "but the term monopoly taken literally means...". Yes, nobody cares. Antitrust is explicitly not just about that.

When my $1000 Galaxy started waking me up with Samsung push notification ads I had not opted in to, I knew I was done with Android.

That is two different statements. HN users are not Joe Average. Apart from working with the Apple Ecosystem, I cannot get enough privacy on Android. The new changes does not mean that Android is acceptable, it just means that the Iphone is also not acceptable, leaving me with zero acceptable smart phones.

Integration with Apple ecosystem, properly designed OS and not mishmash of dozens visual styles.

That’s basically the reason me and every iPhone owner I know buy one.
