Not sure anything productive will come out of a sweeping title which turns out to his subjective opinion about a few UI features being different than what he’s used to, especially for relatively niche operations. It’s unclear what makes him fiddle with Bluetooth or WiFi so much more than average – joining lots of private WiFi networks? – but it seems like this is Apple optimizing the mainstream use-case, which isn’t exactly unexpected.
Notifications are an interesting case because his logical model doesn’t match the system’s (badges numbers are not just a notification counter - for example, my newsreader & podcast app badge unread items), or which apps he’s using which don’t sync notification state across devices as all of the Apple apps and most mainstream ones do, but also what I think of as a war of attrition trying to have the UI cope with abusive app developers. The App Store ToS disallows marketing spam but if the app is pushing that line, you really should disable notifications or, better, delete it and leave a negative review — trying to filter spam is a losing game when you’re doing it part-time and the developers has a team trying to exploit your attention.
