Because, as I said, they don't want to. They don't want to go to the trouble and expense and they don't want to give this guy the attention he wants. Especially since it appears he hasn't done anything except shoot his mouth off on the internet, if their story about him not being AWOL is true. They're getting rid of him in a matter of days. End of story.
The military not wanting to "go to the trouble and expense" really? Wow. Just how expensive and troublesome would it have been to change his discharge to even general...not to mention dishonorable?
And, as for "shooting his mouth off"...yeah, the military is very lenient to enlisted personnel who shoot their mouth off and publicly state they believe the CinC is a criminal and should be arrested. Just everyday occurrences in the military I'm sure. No biggie. Oh..and to go ahead and give him that well earned Honorable Discharge any way.
Sure.
