Everyone that worked in an operational incident response role has blocked some indicator like an ip address or a domain. you don't do gradual roll outs for those either, and i've seen people cause outages by skipping a check or making a mistake. this is similar in many ways to that except it was for a named pipe. This could probably have waited for a canary deployment, but in general the class of content that is being deployed would be deployed right away, I'd be surprised if their practice is considered "bad" by any measure. I've seen Microsoft also deploy email quarantine signatures and defender updates that caused large scale impacts.
Here is a link of what Microsoft did earlier this year:

If they had canary deployments, that wouldn't have happened. I had rules that were causing chaos because of that. Now imagine if defender had a bug that caused it to crash because of a signature update. The impact would be magnitudes greater than what you saw with Crowdstrike. It's really frustrating to see the lack of technical critical thinking and arm-chair experts acting like they know what they're talking about.
