after a decade of dealing with the founder's bullying, i had enough, looking back almost every year there was something. we did handle things privately until it was clear nothing was going to change, the only real change is we cannot buy teensy, a closed source board sparkfun exclusively makes now, maybe they (sparkfun) will stop paying the payments on something that had to agreed to, and have, we'll see.
I understand you're pretty upset with the situation, and I can't blame you.
But I never should be reading about any of this on public forums. It doesn't reflect well on you or Adafruit.
Now an outcome has been chosen for you, without your input. The situation is probably irreconcilable.
That's not the position you ever want to be in. Obviously.
If the situation was untenable, after your reasonable and private attempts, you should have decided to sever ties on your terms. The outcome would have been the same, but you'd be in control of the situation, and wouldn't be permanently leaving things in public view.
I'm sorry for the situation. I'm a real hot head at times, but it's something I've learned (the hard way, over and over again) that I need to control. Business is business...
I hope it works out for you and Adafruit.
