Due to the scale I think it’s reasonable to state that in all likelihood many people have died because of this. Sure it might be hard to attribute single cases but statistically I would expect to see a general increase in probability.

I used to work at MS and didn’t like their 2:1 test to dev ratio or their 0:1 ratio either and wish they spent more work on verification and improved processes instead of relying on testing - especially their current test in production approach. They got sloppy and this was just a matter of time. And god I hate their forced updates, it’s a huge hole in the threat model, basically letting in children who like to play with matches.

My important stuff is basically air-gapped. There is a gateway but it’ll only accept incoming secure sockets with a pinned certificate and only a predefined in-house protocol on that socket. No other traffic allowed. The thing is designed to gracefully degrade with the idea that it’ll keep working unattended for decades, the software should basically work forever so long as equivalent replacement hardware could be found.
