I seem to recall some business where Arduino split in half, that Arduino.cc and arduino.com were different entities, there was a trademark dispute leading to the “Genuino” name being used in some locales, there were some similar yet incompatible boards made, then Adafruit announced they were partnered with Arduino and would be the manufacturer for Arduinos sold in the United States, which then apparently fell through pretty hard because Adafruit won’t mention Arduino by name anymore. There was a brief stint working with Intel to make a couple x86 based boards, which went nowhere because Intel can’t handle releasing documentation about their products, and then they sell to Qualcomm, and now we’re mourning the loss.
