They already have advertising, at least in MacOS. Every time I put on my headphones I get a pop-up ad for Apple Music, and I can't hide iCloud or Safari's constant nagging to get me to use them.
Everyone has their own limits, but I left the ecosystem after Mojave (with this being one reason).
I don’t know, is that really advertisement? These seems more akin to a program’s popup of its new features or that you can also go pro. Sure, nitpickingly these are ads, but they are related to the context, not intrusive, and not coming from a third party.
If anything, it is more analogous to my friend telling me about that vacuum cleaner he bought that he finds a great buy when I bring up the topic of vacuum cleaners. Surely, it is still an ad, but you get the difference.
That’s a mac, and while I agree it is one of those pesky, annoying ones, it is likely more of an oversight/not enough people care thingy to count it as a bug.
I use a mac and an iphone without apple music and never seen anything like that.
