Just sour grapes from Mr. Moran (is that even his real name?).
He had no problem with the highly-invalid Frs. Pfeiffer and Hewko until they showed him the door.
And I'm sure there's no problem with the highly-schismatic "Bishop" who may or may not have ordained/consecrated him.
This happens over and over again.
A man leaves for his own reasons (or gets fired), but the man tries to blame the organization he left, as if he saw problems with them all along, and THEY were the problem.
Even though the man in question (stupidly) was not only a member of the organization, but an active proponent and apologist for the group for 1, 10, or 30 years. Says a lot about you, bub!
I recently had a man break off a friendship with me because he didn't want to pay back a loan. I lent him money so his family could buy a minivan they needed. He repaid me by ripping apart 2 families that knew each other for 10+ years, and were good friends since 2012. There are several spiritual relationships (baptism, confirmation sponsors) between the two families, etc. Our families used to spend time together, worship together, play together, work together, you name it.
But of course the man tries (vainly) to come up with a justification for why he shouldn't pay me back. I'm rich and he's poor, I was enslaving him, etc. Even though he had no problem at all with me just 14 months ago, before I lent him the money. And he never felt the need to break off the friendship until I asked when he was planning on paying me back. Then his first words were "friendship over" as if that was pre-loaded in his gun. He didn't even give me a chance to agree that he didn't need to pay me back

It shows how premeditated the whole thing was.
What Ambrose and the man I described above have in common: They were both involved in relationships of convenience. They were only involved because there was a benefit for THEM. As soon as that benefit dries up, they're outta there.
