What harm have you experienced, other than hurt feelings?
Don't get me wrong, I've had an issues with an admin there because I didn't share their viewpoint on a news story, but that in itself is not illegal and I haven't been harmed as I didn't use the account for commerce. They are guilty of violating an internal code of conduct but the corporation is not going to care about that.
On Twitter, Musk chucks off whoever he feels like. A recent high-profile example was the "Twitter files" report guy. It's his own personal private corporation, he can do what he wants. Same way you have control over your living room. You might invite people over every night to hang out with you, but it doesn't grant them rights over your living room.
I mean, sure, if you really wanted to, you could certainly look into anti-discrimination legislation and so forth, but again, what is the compensation for what discrimination? You haven't lost income or relationships. You weren't discriminated against because of your skin colour, religion, sex, disability, etc.
At best, the employee is guilty of an internal code of conduct violation and you could report that, but they aren't obligated to tell you the outcome of their internal deliberations.
I did read the blog, you made good points, but let it go. You won't win this.
