To the OP, I have been feeling this way about Apple for the last couple years for the reasons you said, and many others. Apple products no longer "just work". I feel like every years, Apple is becoming more and more like Microsoft was in the early 2000's.
I am now scared to do updates. I updated my iPad Mini 2 from iOS 8 to iOS 9 (or maybe 9 to 10), and it made the device almost unusable. A few updates after that led to slight improvements, but not anywhere close to how well it performed prior to the update.
Another change that I have noticed about Apple products in general, is the user friendliness of them has gone down. It seems like I am constantly having to look up how to do simple tasks on their devices. Tasks that were very easy and straight forward before, are not requiring a google search to figure out how to do them.
The intuitiveness of Apple software is not there anymore.
I could probably fill a whole thread page of Apple changes that bother me....
I still think that Apple makes good products and software compared to the competition, but the difference in quality between them and the competition is not big as it once was.
I totally agree with you, I went to apple in 2011 after building my own gaming rigs for years and after finally having enough of Mircosoft I jumped to apple for an easy life. That was Steve Jobs genius making products just works easily for the average consumer. Been having buggy issues sine the 2016 Macos update, but before then never really much of a problem. Very rarely did i suffer a crash since I bought my second mac mini in 14. its a very worrying trend at the moment but hopefully with the move to the new HQ they can focus on getting back to the apple we all love.
One big change that I have noticed about Apple products, is that the huge amount of inconsistency of user experiences. In seems for every post saying their device is great on (fill in the update), there are just as many of people saying they have problems. And it would make sense if it was consistent with a particular device, but people with the same devices are having two very different experiences.
In the past 3ish years, I have spent more time talking to Apple Support about various Apple product issues than I have the previous 20 years of using Apple products. Problems happen so often now, that if I would call Apple, or go to an Apple store for every issues, it would take up a very significant amount of my time.
