In the OP's style,

Sorry, some employees organized?

That's it?

That's the whole story?

No one was harmed? No regulators were mislead?

It's actually quite reasonable for the people to find out about something like this and publicly reach out to make sure these companies are aware of the laws around stuff like "don't retaliate against employees acting in the public interest."

And surprise, if corporate sympathizers misrepresents acts of public service as "impersonation," it is perfectly reasonable to call them out for their BS. We all know no one's concerned about impersonation risks. They're furious about employees speaking up.
