You don't tell or demand another company do something with their own employees. There's more professional ways of dealing with a situation like this.
Request a meeting. Send a calm, collected, professional email to a decision-maker and be sure it's well sourced and factual. Keep things in private.
If the other party decides not to take action, then make a decision if you want to continue doing business with them. Do not keep pressuring them for the outcome you want, do not escalate the situation, and certainly don't drag the dirty laundry out into the public.
Like, what good did Adafruit actually think was going to come from getting into a fight with the founder of Sparkfun? 50 lashings with a wet noodle?
Whatever Sparkfun allegedly did to cause this, Adafruit looks pretty poor in this light. I've been a long time customer of both Adafruit and Sparkfun, and will continue to be - but this is some rookie, amateur, hot-headed behavior from Adafruit.
