Meshcore isn't, the firmwares are proprietary. Meshtastic is, but they whine about trademark stuff all the time and cry when anyone mentions Meshcore in their channels. LoRa radios themselves are all proprietary Semtech turf. I guess it's possible to run over 2.4ghz but the range predictably sucks compared to 900mhz.
That's interesting. That's the first time I've seen a "[deleted]" comment. IIRC, HN would just disallow deleting if somebody replied. Maybe this is from replying on an already deleted comment.
