Glad to see you chime in here. Just curious, is Arduino setup so that the community could takeover if you did somehow go pure enterprise and abandon hobbyists? If I recall, things are pretty open source.
Everything except the name is properly opensource for the OG arduino (Arduino Uno).
For some more recent boards, there are proprietary components and binary tools and blobs - notably the Expressif board packages for the ESP8266 and ESP32's. At least some of the blame for that is with the chip manufacturers and not the Arduino project.
