This seems a little disingenuous. The entire reason that user-serviceable devices aren't possible is that the tooling required to service them becomes more and more specialized as the devices get smaller. It's not a matter of whether or not they can make user-serviceable parts (which why I replied to a comment about things like Fairphone and other modular/serviceable phones) but whether they can scale that and the reality is that 1) it doesn't scale without being so expensive that users can't afford the devices and 2) most users just don't care about user serviceability. So the idea that there are 2 ways to build is a false dichotomy.
