Re: You put your finger on it
And there can be numerous factors influencing a brand's reputation, with hype, innovation, quality, appeal (whether popular, cult or just snob) and length of establishment/reputation being perhaps the biggest five. And those can easily blur together or even overlap entirely. It's quite possible for a product to be quite good, perhaps excellent, and still be over-hyped. And of course, these things can rise and fall. Your example did both, enshittification means plenty have fallen, Google for one *was* the best search once upon a time but is now crap. Hyundai was absolute garbage at one point, but put in the work to at least get to "solid", although I don't know which they are today as a non-driver. And yeah, the list goes on.
WRT Apple, while they definitely deserve most, if not all, of the flak they get, and are insanely over-hyped, I keep buying stuff from them because all of the BS aside, their kit suits my needs best, has been reliable for me for far longer than the hardware upgrade cycles they'd prefer buyers to have,[1] and also fills in a few wants.[2] That said, I do wish they were using those piles of cash to do real R&D, make their kit even slightly more affordable, or even just pay workers more than give even more cash to execs/major shareholders, but that's another discussion entirely.
[1] It's partially for economic reasons, but also because I simply don't see the point in replacing anything that is still fit for whatever purposes I'm throwing at it.
[2] In some regards, I find that their baked-in restrictions less chafing by far than feeling confined to their kit because the alternatives mean *more* compromises that I'm unwilling to make. I want at least the option to use Linux or de-Googled android for everything without having to give up certain essentials.
