I assume the same type of person might just disable the beacon..

Well there’s a button on the drone to disable the altitude restrictions, I’m not sure why you’d disable the ADS-B transceiver unless you are just trying to cause trouble.

No. Most aircraft don’t have ads-b receivers and TCAS doesn’t use it.

I’m not sure what the percentage is, but at least some aircraft will have to have ADS-B Out in 2020, per https://www.faa.gov/nextgen/programs/adsb/faq/#g2

I like the idea of requiring ADS-B Out on drones. For those aircraft with ADS-B In, it introduces the possibility of seeing drones sending ADS-B Out. And others with ADS-B receivers will be able to see and identify them.

As an additional step, drones could be required to use ADS-B in for aircraft avoidance.
