> Being reliant on the hardware manufacturer (or network operator?) for OS updates is the crazy world we live in.

Being reliant on a single OS permanently nailed to the hardware is no less crazier. I'd like to be able to install another OS on a vulnerable device, it would help tremendously and not only with the security of that specific device.

Now I've got some expensive paperweights that I can't even use as such because every time I see them I have the urge to throw them in the trash can.

Provide a way to unlock the phones and a standard BSP, it should be the law.

I switched away from my flagship Samsung tablet when they pushed it to quarterly updates, meaning security issues often went unpatched for a while. In the fine print of the "X years of updates" they mention that they switch devices to updates only every 3 months and then every 6 months down the road.

I hoped with a move to Fuschia, Google would attempt to fix this, but unfortunately Fuschia on mobile is dead.

That's always the case, even on Windows, even on Linux for closed-source third party drivers. The only exception is macOS because Apple insists on writing the drivers themselves - that was, in addition to Soldergate, the reason why Apple dropped NVIDIA.
