Would this have changed something for this specific problem? I usually 100% agree with you fwiw, I just don't think this would've helped here because it seems like an almost "non update"? Most people claim there has been no update to the software, and no prompt or option to update it or not
It's a file that was downloaded from Crowdstrike's servers, which have presumably been whitelisted in the firewall, and used to configure the software. Of course it's a software update, regardless of whether the file says .exe or .dll or .sys or .txt, and regardless of whether there was a prompt.
Again, the same team in most enterprises wouldn't dream of letting you have an auto- updating Firefox Nightly, they know how to configure software so it doesn't phone home for updates or is blocked from phoning home.
