I'd say that 'jettisoning QA teams' is a mischaracterization. The role is still filled, it's just evolved a lot since the windows 8.1 (and prior) era. Similarly, I'd say that 'Trusting telemetry alone' is also a mischaracterization. From where I sit, both roles are combined. The output is a far smoother engineering process and a higher quality OS. You mentioned 'corner cases [being] unaddressed' but I've witnessed the exact opposite: most of the criticism I hear about Win10 has nothing to do with quality.
