Good, imo. Rest of the world has been running 5g and planes haven't fallen out of the sky. There's something like 200MHz gap between the frequencies in question and that's wide enough to drive a truck through. FAA should prove there's a risk if they want to delay the rollout, and they haven't. Glad their bluff is being called.
Athough I won't be using 5G until I get a new phone 3-4 years from now, I'm happy they did that. Big government can't control everything.
