Probably harder to disrupt (cell networks, WiFi, and Bluetooth are all specialized, relatively low power radios after all).
In the US, legal radio usage would be easier to eavesdrop on (I believe encryption is effectively banned). But if you're willing to ignore that detail then it won't be easy to eavesdrop on you.
It would be trivial for a state funded adversary to triangulate broadcasters though.
Jamming is a big step I don't think we've seen in the US so far and I'm not sure the police have that tech readily at hand. Inherently though you're going to want to be able to include people into the network easily which already opens you up to eavesdropping of the public channels. For purely public broadcasts radio is nice because anyone can listen and it doesn't reveal location in the network.
