> Coolest thing about the Helium LoRaWAN offering is that you can buy a $20 ESP32 microcontroller with Lora radio on Amazon, write some software, buy Helium data credits and use it anywhere helium has coverage.

Or just go with the free TTN. But I do agree that it's good to have icentives and I'm quite glad somebody is rolling out a large scale LoRaWAN.
