Policies can differ from workplace to workplace. HR policies you're familiar with may be different elsewhere.
People often get fired for things that have nothing to do with the quality of their work, like budget cuts or mergers resulting in redundancies.
You were dismissive earlier, and responded to a post of mine with gifs, so I do want to resolve an important question. Do you agree that people should be able to assess political bias independent of their own views (IE- should someone who is among the most conservative 20 percent of the population recognize that they're more conservative than the median voter?)
To answer your question, I think she's a whistleblower. She had a complaint, and it seems there's substance to her concerns, in that there were not enough therapists with experience in gender issues to process claims.
If she was complaining about something with a different political salience (police officers drinking on the job) I suspect her current critics would accept this level of evidence that some reforms may be helpful.
One way to consider this is the extent to which a newsroom is politically diverse.
That would help determine if ostensibly mainstream outlets are part of the liberal media.
Good for her.
If the story is real, a few things matter.
It is a bit obnoxious for an HR person to call out a new hire for their preference in sandwiches, and for new coworkers to snap fingers in affirmation.
It does suggest different norms within an ostensibly mainstream media outlet than in the larger population.
It's also important if it happened, and people in the media incorrectly reject it.
For Adam Rubenstein and his friends, it would be a matter of honor if people call him a liar when he's telling the truth.
It's bad if people within an industry don't understand its biases.
It's bad if the media is wrong. Their main job is to be correct, and to not make mistakes ordinary people make because the civilians lack the professional training to avoid blindspots and cognitive fallacies.
The media is also supposed to help people make sense of the world, so it's a problem if many of them don't understand it.
