This episode brings up the psychological issues that transgender people face. It is not inappropriate to call it mental illness. This acting out against the world is a cry for help. This person admits the connection with their quote "be gay, do crime". It is possibly a response to being visibly transgender, and coping with everyone constantly reacting to you. None of this is helped by the egging-on in their social media bubble. It is not good optics, but it needs to be addressed.

To clarify, I think (or hope) this is what you're trying to say; being transgender is not a mental illness. The effects of either pretending to be cisgendered, or attempting to live life as the gender you identify can definitely lead to mental illnesses (depression, low self-worth, anxiety, etc.). I can't think of one trans person in an unaccepting household who didn't develop a few bad coping mechanism for their gender dysphoria. Luck decides if that coping mechanism leaves you scared for life (physically, mentally, socially), or if you're able to eventually unlearn it after you've gotten away from your toxic childhood environment.

Not to mention the ethics of spreading the PII of someone who you suspect to be mentally ill (who claims to have hacked your company).

Pretty sure that his opinion and poster is not the threat actor’s doctor.

That's fair. I mean that if this person's claims are truly dubious and they seem to be seeking the spotlight, then giving them the spotlight could exacerbate their derangement. That's useless for Okta, sad for this person, and dangerous for others.
