I've been using BirdNet-Pi for a while and it's great fun. I'm a little confused about the commercial offering from BirdWeather - the PUC looks like a neat product, but I understood most of the BirdNet stuff to be Creative Commons NonCommercial. Maybe there's some nuance about how they're using it, or maybe some pieces have a more lenient open source license?
