I think the most crucial takeaway for me is that NTSB finding of how often this was almost happening for over a decade. That's guilt by inaction at that point. I understand that some flights need the security of being un-broadcasted, but I struggle to think they happen so often. It feels like the FAA is really saying that they're raising the bar for being able to turn off the ADS-B which I agree with completely. Too bad it's 10+ years too late.
