Well, this exact problem is more apparent in smartphone market: there are literally no options with screen smaller than about 5.5". So yes of course people buy whatever crap market has to offer because the only other option is not buying at all.
People complain about the new thinner macbooks all the time. The keyboard is atrocious, the touchbar, the dongles... Seems to me they would've totally bought a modernized 2015 model if it existed.
People complain, I don't think it means much. If you want to know what is really going on then look at the sales figures. Apple's market share of desktops and laptops has been broadly consistent for a long time.
