IMHO the Apple ecosystem was always about getting people hooked on one of their products and then up-selling them other products and services and thus set them up for a lifetime of buying the latest and greatest from Apple at regular intervals.
In the past few years, I've seen many long time Apple users opt for alternative brands. And not just because of the price points. I have friends that now have Android phones and windows/linux laptops where just a few years ago they would have been de-facto iphone and macbook owners as well as own a whole range of misc apple branded products. Apple had a really nice business tapping into these people's disposable income and it has been evaporating for a while now.
By squeezing their iphone and mac book user base too hard, they have started to bleed users. This is bad news because it means the upselling business is going to dry up as well. People with an Android phone are not going to want an iWatch or iCloud subscription. They are also not going to order anything in the Apple store or sign up for Apple Music. And raising prices there is going to shrink the user base even harder.
Apple has neglected some of their core product lines and especially their recent desktops have not gone down well with users. The pattern is the same across their product lines: sales revenue is up but volumes are down for the last few years and not just because of the price. They make more money with fewer users. Except, now they are making not as much money as they hoped with even less users than they expected. They squeezed too hard and the numbers no longer add up.
The fix is simple: they need to change course and get volumes up again by making sure that they have attractive premium products that people can afford. You don't get service revenues up if your user base keeps shrinking. A few well positioned products at the right price point could easily bring back lots of users that have dropped out of the ecosystem. More of the same is not what is going to make that happen.
