While I think he felt disrespected is one part of this, I also think he feels he can better monetize this if he does his own ceremony/party... as for the latter is probably him getting horrible advice and following it, which would be par for the course for him.
I just think it was an awful decision on his part. Not attending just reinforces how much of a jackass he really is.
