I don't see how you get that from them being disappointed in the clergy who are guilty of sexual abuse of kids. They said "certain past clergy" so as not to indict all priests everywhere since it was only certain past clergy who were outed in the 2018 release of all their names. A lot of them already dead. What about that makes you think it smacks of "say nothing and ignore" since that's the complete opposite of what happened in 2018 when they released the names, defrocked and charged those who had claims made against them?
