Do you have any information about the privacy achievable by Meshtastic?
From a quick glance it looks like it‘s using static NodeIDs derived from the Bluetooth MAC address in the always unencrypted Packet Header.
So not only can you sniff these messages from far away at greatly simplified complexity when comparing to cellular communication, but also tie it to the hardware that you carry with you.
Mesh networks sure have its uses, but I‘d be wary of their offered privacy in the presence of adversaries you could be facing at protests!
