I wonder if part of it is the association with Pine64. They've delivered some fantastic stuff that people didn't think would be done.
Also launching satellites with LoRaWAN on them doesn't look so hard any more. I was looking into it the other month and you can get prototype kits with the correct transmitters very cheaply.
While in-depth details seem light, is the absence of such criticism a positive indication regarding the integrity of its base security and privacy principles?
