Is Vigano pen-happy?

My mother used to say that about me when I was little.

I used to write letters to everyone, relatives, the pope, politicians, movie stars, and so on.  When I wrote to relatives, what I said would get back to my mother and she would freak out and yell at me, "You're pen-happy!"  It still cracks me up.

That said, I wonder if Archbishop Vigano is 'pen-happy'?  

He wrote another  public letter - open letter - to McCarrick calling for him to repent publicly.  On the surface it reads very holy, but is it appropriate for a bishop to supercede the Vatican courts and call for a public confession, repentance and penance from McCarrick?

Why is Vigano so public with his information and judgement now, when he knew way back when and was glad-handing and congratulating McCarrick in photo ops and at banquets?

Dear Archbishop McCarrick, 

As has been reported as a news by the Congregation for the Doctrine of the Faith, the accusations against you for crimes against minors and abuses against seminarians are going to be examined and judged very soon with an administrative procedure.

No matter what decision the supreme authority of the Church takes in your case, what really matters and what has saddened those who love you and pray for you is the fact that throughout these months you haven’t given any sign of repentance. I am among those who are praying for your conversion, that you may repent and ask pardon of your victims and the Church. 

Time is running out, but you can confess and repent of your sins, crimes and sacrileges, and do so publicly, since they have themselves become public. Your eternal salvation is at stake. - Finish reading here.

As the NCRegister article makes clear, Pope Francis suspended Archbishop McCarrick from public ministry last June, pending the completion of a canonical process against him.  So why is Vigano now jumping the gun and calling for McCarrick to go public?  Something is off.  Many Catholics online celebrate Vigano as a saint, praising him for his courage.

Something is off.
