That's a reasonable take to an extent, but underlying all of that is the assumption that Meshtastic should be trying to scale up to support hundreds or thousands of active nodes on a single mesh. Since that's clearly almost impossible to achieve with an ad-hoc network of low-power LoRa radios, it's not entirely fair to criticize Meshtastic for not inventing a revolutionary solution to a very hard problem.

It would be more fair to criticize Meshtastic for not being clear enough about the tradeoffs and limitations inherent in a low-speed ad-hoc mesh network, and for not actively encouraging people to seek other hardware and software if their use cases are not well-matched to what Meshtastic hardware is capable of. A one size fits all solution simply isn't possible, and Meshtastic can't be the right answer for everyone.
