> Just don't mention MeshCore anywhere around Meshtastic, or they'll kickban you.

Thats not the problem. And Ive also mentioned Meshcore as well on their discord with no threats of banning or anything of the sort. Ive also seen people come in the group, with "Meshtastic sucks and Meshcore is best", and the worst by admins was 'we have no problem discussing but that tone was overly harsh'.

Liam Kottle, the head of Meshcore ran the first Meshtastic map from grabbed MQTT data. However, he was grabbing and saving everything, including public channels, direct messages, GPS, telemetry. Everything. 1.5y ago, people were going to his map and snooping on Defcon Meshtastic DM's, since even 1 node who reported MQTT would send everything. And then, DMs were simply filtered by the UI, but were effectively encrypted by the same shared key.

Normally there was a general expectation that the data was ephemeral. Liam basically created and caused this data problem by saving and making available everything sent to MQTT.

Meshtastic devs ended up having to tighten down the public MQTT broker a bunch. They also made the client on phones be more restrictive what was done and sent to MQTT. Also made "OK to forward MQTT" flag in the data packets too. And 2.5 introduced PKI TOFU for direct messages to prevent leakage.

Aside the personnel difficulties, the technical issues with Meshcore are similar at node capacity too. Messages still dont get delivered near capacity. Core requires infrastructure nodes. Its more like APRS+LoRa than anything like a mesh.
