I felt exactly the same when I read about the outage. What kind of CTO would allow 3rd party "security" software to automatically update? That's just crazy. Of course, your own security team would do some careful (canary-like) upgrades locally... run for a bit... run some tests, then sign-off. Then upgrade in a staged manner.
This is a great point that I never considered. Many companies subscribing to CrowdStrike services probably thought they took a shortcut to completely outsource they cyber-security needs. Oops, that was a mistake.
