Earlier quoted context omitted.
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 cleaner…
If I got an advertisement for a new iPhone every time I woke up my current one, IMO ‘intrusive’ would be too kind a word to use, too.
I also think “related to the context” is debatable. Headphones aren’t only used to listen to music.
