My critics and re-focus on Apple, Google and Microsoft ecosystems, steam from having discovered the alternative universes happening outside Bell Labs, being a fan of UNIXes that went their own way like NeXTSTEP, NeWS, A/UX, Irix, Solaris, instead of being yet another UNIX System V clone in user/developer experience.
Not sure if GNU/Linux has learned much from ChromeOS/Android UX, given the current state of desktop fragmentation.
