Do all drones do this now? Is this required by law for manufacturers to implement?

Had a friend who worked on designing systems to pick these signals up around airports

Drones over 250 grams or for any drone operated commercially under part 107 registration is required. But, its easy to just build your own or desolder the id chip if you dont want it.

It’s easy to build your own, but it’s impossible to build one to be as stable as a DJI one, or as cheaply. E.g. with an FPV drone hitting the lens would be much harder (but you could use spray instead of a stick to make it easier). Removing remote id ‘chip’ is plain impossible since it’s implemented by the same radio that does video link.
