Strongly agree with you. When Apple things fails to 'just work' it is a nightmare. I used to have this issue for downloading MacOS updates. My internet wasn't too fast and it would get interrupted and restart from zero. Who can't do download resume in the last 10 years, I would assume only apple. My office network was faster and we also had those cache server, it worked for everyone except me. MacOS provided zero hint and it 'just failed to work'. Office internet was fast enough to download in multi MB/s yet Apple update weeks after released (so I don't think there was rush and it was US night) would have speeds 50 KB/s to < 500 KB/s and of course you can't choose a mirror or whatever cause it 's meant to 'just work'.
This is just one example that I vividly recall. The simplest of operation downloading of an update, only apple can make it as big a nightmare as it was. Now they do a lot of things fabulously but when the fail they just fall on their face and ignore it or they would fail where I can't even imagine how to fail this bad.
The latest blunder (again download), my iPhone lost it's wifi after a fall and wow! behold you can't download an update over cellular. Apple will make you save your money by not using your expensive cellular data after all it's so much more expensive than your $800 phone.
