Practically, even if Microsoft did want to make the device disassemble friendly and was even willing to spend the engineering dollars to make that happen, I think they'd be turned away by the fact making a "polished" device that's easily disassembleable would increase failure rates. The bonded materials greatly increase strength over a set of spaced screws/latches into thin material.
If you have to use the word /honestly/ in your communications, this leads readers to believe that the remainder of your information is falsehoods.
Also, please link to the studies & polls that show %95 of users do not want serviceable, fixable, or user upgradeable laptops.
I doubt the veracity of your claim.
All these higher end laptops all come with pretty decent warranties so for a couple hundred bucks you get it either repaired or swapped out. Then again, I'm a tone deaf American with a large amount of disposable income...
Right to repair is also usually centered around software, since that's the crux of the argument used by companies like John Deere. JD technically isn't telling people they can't repair things, just that they can't "hack" their software (an "IP infringement"), which so happens to be a necessary step in repairs.
I have a legal right to repair my own products or have a third party do it, but because the manufacturer is under no obligation to make it easy everyone gets screwed.
