In one or another way, Prevost is part of the problem. So you should ask others that question. Perhaps at a session of an imperfect council that you should have convened a long time ago and still need to and should convene. The sooner the better.
No doubt it needs to be dealt with, however, the last thing the Church needs is a Vatican III in which the deck is stacked even more than it was previously. They need to implement the true Faith and control any malignant 'predispositions'. A novel notion might be to curb their vain egos and let the Holy Spirit flourish for a change.
At least somebody is saying something about it to Leo. He'll ignore it, of course, and that's even if he actually gets the letter and deigns to read it. But at least one of his brother Bishops has made the effort to warn him directly and explicitly. He cannot claim ignorance.
One must applaud those who take their position seriously enough to point out the obvious.
