It still sounds like something I’d not be interested in: having to be so defensive around the os. Apps are already annoying, but if you can’t trust the OS itself, then why bother with it at all?
Of course, the obvious solution is to run a good Linux distro or OpenBSD, but frankly it's hard to live with purely just Linux for me. ChromeOS has the advantage of things like near perfect High DPI support.
This has never happened in the ~20 years I have been using Linux and other OS. Linux went from "meh" to just as good pretty recently, imo.
Furthermore, this is just a usability consideration. Don't forget that all other OS become more and more closed, more and more about collecting private data, and more and more about proprietary app stores.
