They don't need to ship anything new and they have the perfect excuse to focus on improving both their OS and their processes that allowed such flawed things to reach their users.

You absolutely can do regular updates that are high quality. You just can't do them in an environment that's deadline driven, or which gives PMs too much power over what dev teams work on.
But you do have a point: it should be product driven not feature driven.
Usually fixing bugs requires access to specific repro machines, and bricking might require access to a lab with jtag style hardware.
