I'm not sure I really agree with the principle of the idea that apples products are getting worse in general. There's always some products that work, some that don't and some that don't at first - but do after refinement.
For example, 2-3 years ago I thought OS X (now macOS) was really going down hill, far less stability, performance stagnation and no clear direction. Turn to 2016 and I think Sierra is the most stable and reliable macOS yet, also we now have much 'better' standboxing, protected core system storage, better battery life and an interesting file system on its way. Now, look at the iPhone 7+ - it's a great phone, it's in my opinion the best phone they've ever made, it's not perfect, the camera is good but it's still a phone camera and thus requires a lot of light and a nice clean lens to take a decent shot, its battery life is excellent compared to most other phones - you can quite happily go two days between charges unless you have something setup poorly (like a polling email account etc), iOS is more responsive and stable than ever, we have public and developer betas and finally Apple actually respond to bug reports from the feedback tool (not every time, but when it's something worth investigating).
The retina MacBook is a lovely replacement for the MacBook Air, yes it doesn't have enough RAM and could do with a bit faster CPU, but it is a truly portable, usable machine.
Since the introduction of the 5k iMac, there's been no turning back for me, I have an early 2015 model at work and late 2015 at home and they are simply a joy to work on, not just the wonderful screen but the CPUs are rarely maxed out, the upgraded GPU in my home machine easily plays any game I want to play.
The bad is that the MacBook Pro is undeniably over priced if you want to spec it out, the Mac Pro is long overdue an update and they in my opinion should have retired the Air and offered a higher spec MacBook.
On the software side of things, we have a larger than ever open source software community contributing software usable on OS X and the range and diversity of games available of macOS has grown at an amazing rate over the past few years, look at the titles on steam, gogs and the App Store - it was only 2-3 years ago you really had to use wine and friends to play such games. iTunes still kind of sucks, it's UI/UX is a lot better than when Apple Music first launched but the app is still very slow and heavy when you have a large library, but Apple Music itself has very quickly gone from being a wtf is this product to replacing Spotify for me thanks to its integration across devices, better streaming quality (or so it seems) and it's better range of full albums.
Tldr; some things work, some things don't, I think things are better than ever regardless of failed experiments or some product lines that are outdated.
