Personally I don’t think they have any responsibility to build such a system, or even have it function properly. By “weird flex” I was specifically referring to the “We are confident that this system fired and sent alerts” line.

Obviously my view is anecdotal (especially the whole “No one got any sort of alert” part of my original comment), so take what I say with a grain of salt!
