You're doing some aggressive assuming. Talking about a topic I haven't touched on. Perhaps you only read a few words of my post.
Here's an example of what could be improved. In 2013 my $3,000 Plus CTO MBP was delivered with four dents in the case. Fortunately I was wise enough when placing the order to specify in store pickup.
Upon arrival Apple notified me and I went into the store. Instead of taking it home I was anxious to see it so I inboxed it in the store. With three Apple associates standing and watching they saw the dents in the case as I was removing the clear protective wrap. Each dent was larger than a dime in diameter and at least 4mm deep.
The impact on me was after waiting eight weeks for it to be built, Apple advised I would have to start over. That involved charging a second computer to my credit card, or waiting three weeks for the damaged purchase to be credited back. I ordered immediately.
The following year ... That new machine had defective WiFi rendering it useless while traveling which I do 24 days per month out of state. So again Apple cost me time and money.
Not to mention other incidents in the last five years. All related to poor quality OS upgrades.
Some is to be expected I'm not looking for perfection. Just ship what works.
The prior fifteen years I bought twelve new Apple laptops which performed like Apple loves to brag. "They just worked " and they did.
