What does it mean to "open up" an operating system in this context? Do they mean something like the possibility to intall other OSes on their devices, or that the app stores needs to be more open? I'm guessing it does not mean they have to start open source:ing parts of the OS... or?
I would love if device makers were forced to open up their hardware to other OSs. Unlockable bootloaders for all as well as allowing users to install their own signing keys so secure boot can remain enabled.
Granted, there would still be black box firmware required to use half the components inside, but that's another battle.
This should be a right of the consumer that purchased the hardware. Same goes for gaming consoles. You used to be able to officially install Linux on a PlayStation.
I am almost certain there would be two major impacts from that. The first being that operating system development would slow to the pace that the community wishes instead of having big money behind it. And the second is that security updates would come quite a bit faster.
Edit: I figure brand new major features would be slower in coming. But security would be improved.
The operating system that runs most servers, a lot of them doing web cloud and networking, with high levels of security (developed by security companies) is open source, the *BSD distributions and also Linux.
But I also have doubts if this is the right move.
