It was my comment. I deleted it, but I was surprised to see the ghost of my comment.

Deleted it because it was a shallow complaint about LoRa being proprietary. However, looking closer, it's not that bad. The physical layer is unavailable, but the link layer protocol spec is downloadable by anyone. Meanwhile, DASH7, an open-source alternative, requires you to be accepted into the alliance before letting you download the spec. Might be a simple thing, but they do advise requesting membership with a company or university email.
