Jon,
the HS is not behind 10’s of thousands of disperate heretical ecclesial communities.
Also from then Card Ratzinger,
Excerpt
“…to be a Church the community must be “legitimate”; they are legitimate when they are “united with their pastors”. What does this mean? In the first place, no one can make a Church by himself. A group cannot simply get together, read the New Testament and declare: “At present we are the Church because the Lord is present wherever two or three are gathered in His name”.The element of “receiving” belongs essentially to the Church, just as faith comes from “hearing” and is not the result of one’s decision or reflection. Faith is a converging with something I could neither imagine nor produce on my own; faith has to come to meet me. We call the structure of this encounter, a “Sacrament”. It is part of the fundamental form of a sacrament that it be received and not self-administered. No one can baptize himself. No one can ordain himself. No one can forgive his own sins. Perfect repentance cannot remain something interior—of its essence it demands the form of encounter of the Sacrament. This too is a result of a sacrament’s fundamental structure as an encounter [with Christ]…”

Protestantism made themselves. They are 100% manmade… by Luther, Henry VIII, Calvin, Smyth, etc etc. Therefore, then Card Ratzinger is saying, that’s NOT legitimate. Ergo those who do that aren’t legitimate
