So here is what I’ve been able to gather. Pope Benedict knew, of course, about the abusers in the Church. He tried to do something about it and did impose some sanctions on McCarrick and some others. However, the conspiracy of abusers was too strong and he was never allowed to do anything serious. Hence his comments to the visitors who brought complaints of abuse to him in person that his power ends at his door and he is impotent to stop the abuses. His position was like that of the Queen who can’t stand up to the evil Prime Minister (a.k.a. the head of the conspiracy.)
Benedict had to resign because the conspirators wanted him out. Francis was brought in because he has an affinity with the conspirators. The gamble is that he will be forgiven a lot more by the general public because of his progressive bleatings on a variety of issues. And the gamble is paying off.
Bluntly put, Francis is never going to do anything to the conspirators at the highest levels of the Church because he’s one of them.
I’ve read a bunch of stuff from obscure places like “National Catholic Register” and others for weeks to figure this all out. There is an added bunch of complexities like financial corruption and internecine power squabbles but I don’t care about them right now. I care about abuse. Every large organization has power trips and money shadiness but none of them end up raping kids and abusing youngsters en masse. Except for this one. There’s something clearly specific to this particular organization that makes it a hub for sexual abuse of boys and young men.
