Your link leads to an article that cites the Guardian....a filthy Marxist rag.I stopped reading right there.
However, the Guardian -- like the whole filthy, gay-enabling Left in general -- wants nothing more than to smear the whole Church with this slime, and especially our upright and honorable Pope Emeritus Benedict. It is very much part of their plan to take down the "straightest" of the institutions which have always opposed sexual vice: the Catholic Church; the U.S. Military; the Boy Scouts; next up probably the Southern Baptist Convention or the Mormons.
As I understand it (somebody correct me if I'm wrong) all the Curial offices are technically "sede vacate" too, until the next pope makes new appointments. It may be that Benedict's abdication is his way to clear the decks, and empower his successor to depose those who need to be deposed.
