> You don't tell or demand another company do something with their own employees.

Depends what they did. Let's check the forum post…

> they had created and promoted hate sites, photoshopped images, and harassment targeting limor, me, and others at adafruit. this was done on company time, shared, promoted.

Ok yeah if a company is sharing bigoted photoshops of my likeness, yes, I'm gonna demand that they discipline the responsible employees. Obviously.

I don't have any reference point for what "hate sites, photoshopped images, and harassment [meriting HR training]" constitute, but if it's anywhere near as bad as it sounds, sure, escalate the situation and air your dirty laundry in public. This is unacceptable behaviour, and apparently it went on for years. When you're being publicly harassed, you have no duty to indefinitely restrain your response to private, polite emails.

It sounds like the allegations are for things that was be illegal in nature.

I think the expected way to handle something like this would be to write the calm factual email. If that goes nowhere then sue them. I don't think the public airing approach is the right one.
