I'm not saying it's easy, I'm saying they should have solved it anyway. For a company that prides itself on (and charges for) high quality user friendly products, reliable software upgrades should be foundational. The double-edged sword argument only makes sense if you assume it's impossible, when in fact it's only the preventable (given Apple's control) accumulation of cruft that makes it expensive. Upgrades certainly would have made a better investment than removing headphone jacks, or adding the touch bar, or almost anything that went into High Sierra.

Yeah, I'm an idealist. Sue me.
