You can see how the blade's mounting shaft bends in the slow-motion pictures. Speaking from experience, it doesn't take much to throw the shaft of a table saw out of whack, and with a table saw balance is everything. The first thing you notice about the difference between the good old ones from the '50s and the low-end modern Chinese ones is how smoothly the old ones run, which translates into a cut that barely needs sanding.
My point, however, is that the detector is either set to a hair trigger or will not stop a dry finger. In the first case you have nuisance tripping. In the second you lose your finger. When a safety device fails, the manufacturer tends to get sued and lose. Therefore they will be set to a hair trigger, and after a couple of random false trips, the devices will get disconnected, law or no law.
