I think the wider societal impact from the loss of availability today - particularly for those in healthcare settings - might suggest this isn't always the case

Availability of a system that can’t ensure data integrity seems equally bad though.

Tell that to the millions of people whose flights were canceled, the surgeries not performed, etc etc.

What is the importance of data integrity? If important pre-op data/instructions are missing or gets saved on the wrong patient record which causes botched surgeries, if there are misprescribed post-op medications, if there is huge confusion and delays in critical follow-up surgeries because of a 100% available system that messed up patient data across hospitals nationwide, if there are malpractice lawsuits putting entire hospitals out of business etc etc, then is that fallout clearly worth having an available system in the first place?

How does crowdstrike protect against instructions being saved on the wrong patient’s record?

Huh? We're talking about hypotheticals here. You're saying availability is clearly more important than data integrity. I'm saying that if a buggy kernel loadable module allowed systems to keep on running as if nothing was wrong, but actually caused data integrity problems while the system is running, that's just as bad or worse.

Or anyone who owns CrowdStrike shares.

They’d surely have used some kind of Unix if uptime mattered.

before you get all smug recognize that linux has the exact same architecture, just because it wasn't impacted - this time.

Too late, I was born smug.

If Linux and Windows have similar architectural flaws, Microsoft must have some massive execution problems. They are getting embarrassed in QA by a bunch of hobbyists, lol.

I'm sure the people who missed their flights because of this disagree.

Or families of those who die.
