^It's a combination of both. This reminds me of a similar (certainly not the same but some similarities) when a company came out with a radar jammer and the FCC stepped in. The "device" did not emit any signal but whatever it did, it confused the radar gun. Ultimately the FCC decided back in 2020:
***ALERT***
Federal law prohibits the operation, marketing, or sale of any type of jamming equipment that interferes with authorized radio communications, including cellular and Personal Communication Services (PCS), police radar, and Global Positioning Systems (GPS).
Jamming Prohibited
Signal jamming devices can prevent you and others from making 9-1-1 and other emergency calls and pose serious risks to public safety communications, as well as interfere with other forms of day-to-day communications.
The use of a phone jammer, GPS blocker, or other signal jamming device designed to intentionally block, jam, or interfere with authorized radio communications is a violation of federal law. There are no exemptions for use within a business, classroom, residence, or vehicle. Local law enforcement agencies do not have independent authority to use jamming equipment; in certain limited exceptions use by Federal law enforcement agencies is authorized in accordance with applicable statutes.
It is also unlawful to advertise, sell, distribute, import, or otherwise market jamming devices to consumers in the United States.
The use or marketing of a jammer in the United States may subject you to substantial monetary penalties, seizure of the unlawful equipment, and criminal sanctions including imprisonment.

And then on top of that, individual states came out with their own laws (which I am 100% positive they will do the same for drones).
California Vehicle Code (CVC)
§ 28150 makes it illegal to:
- Equip a vehicle with a device that can jam, scramble, neutralize, disable, or interfere with police radar, laser, or other electronic speed-measuring devices.
- Use, buy, possess, manufacture, sell, or distribute such a device.
A violation of this code is considered an infraction, which can result in fines and penalties. This state law reinforces the federal prohibition on the use, sale, and possession of radar jamming devices within California.
