Yes, Apple considers general purpose computers a legacy technology and more so a legacy business. Apple would much rather be in the locked down, small screen appliance business, i.e. computing devices made for techno-phobic user base.

But it may backfire spectacularly on them, since once they abandoned general purpose computers and server operating systems, their cloud services will/are suffering as a consequence.

Really, if you are a software developer not specifically developing for Apple platforms you are much better off building yourself a Linux system at this point.
