The problem is people feel trapped into buying Apple only because they got used to MacOS. I'm sure not many would bother to keep using these outdated 2015 MBP if they could simply install MacOS on a Thinkpad X1 like you do Linux, for instance.
My theory on Apple's design process with the MBP is they put all their efforts on the first 60 seconds with the product. The touchpad is the first thing you touch in a store, the bright colorful screen, and the very cool look the flat keyboard gives to the whole machine contribute a lot to the first impression.
The finger pains, the electric conductivity and heavy weight of the aluminium, the reflective screen, those are things you suffer from only once you've already bought the product.
