I mean, actually imagine the legal proceedings involved.
Our intrepid hero Han files a suit on the basis of "they might have told people that I wrote a bunch of terrible shit, I mean yeah I wrote it and they didn't actually tell anyone, but they made me apologize under my pseudonym which is basically blackmail." I'm not a lawyer but that sounds like a heavy lift.
Now because they haven't actually doxxed him and because his case rests on the huge amount of harm done to him if his identity were to be made public, he obviously can't file the suit under his real name. It gets tricky cause of the Confrontation Clause of the (looks it up) 6th Amendment, where you get to face your accuser. But over the years the courts have carved out certain exemptions or allowances, e.g. children giving testimony in abuse cases.
So now you have all these legal documents with the name HanAssholeSolo peppered in them, and the plaintiff is showing up with whatever the alt-right equivalent of the V For Vendetta mask is. If they don't allow cameras, we could be talking about a courtroom sketch of some dude in a suit wearing one of those creepy anime girl masks or a Pepe head or something.
Can't even imagine what the testimony would be like, but in all likelihood you'd have a judge spending weeks getting familiar with the various memes and norms of a particularly dumb corner of the internet.
On top of all this he'd have to ask for damages that would bring down Time Warner, so he'd be walking into court asking for what, $10 billion?
Tell me that wouldn't be entertaining.
