Meshtastic is GPLv3. So all source code will always be available.
Meshcore is MIT licensed. And closed source applications already started to creep in. See the smartphone apps and the T-Echo implementation. This has already the classic smell of ham radio projects I honestly don't want to support.
The maintainers of MT are friendly. The people using it - not all of them. Like all community driven projects.
It seems like there are some people in the Meshtastic and MeshCore community who have it out for each other, for reasons beyond me.
I've only personally tested Meshtastic, and from a technical perspective, it still feels very beta, and I wouldn't put critical communications on it. However, it's a fun introduction to LoRa and long range low power RF, and can be a fun way to communicate much like I think amateur radio was to its early adopters.
I think one thing that causes a lot of community strangeness is the strong push by some to make it what it's not, like some doomsday-proof communication system that will outlive cellular networks and atomic bombs. It could be useful but requires skilled operators and coordination to work well (like using different frequencies and coding at events for much more bandwidth).
I saw some twitter-like shit comments on chi-mesh while visiting family in IL.
But I've seen nothing but friendly interactions on the SF bay mesh which is much larger and thriving.
Nothing seemed particularly toxic, not on either of these meshes. Considering it's an open system anyone can say anything on, I'm sure it'll devolve into chaos as it gets more popular.
But when it comes to toxicity I'm going to assume you're either referring to the Discord, or making shit up. Discord having its roots in gamers is known to be a dumpster fire and I expect nothing less than toxic behavior on any Discord "server".
I do not understand why people spend time on Discord to play with Meshtastic though. Play with the mesh, that's the whole point.
