If you believe the Holy Ghost intervenes in a valid conclave and that the Papacy is a Divine office where formal heresy CANNOT be tolerated, and, as the Pope is the Vicar of Christ on earth inspired by the Holy Ghost and not allowed to be in grave error, ( In all teaching- not just ex catherdra) then the Siri "conspiracy" is a circuмstance that must be considered-"Good" Pope John XXlll was a known Italian freemason and unelectable in a valid conclave.
Pope Pius lX was a liberal and the freemasons and Jєωs WANTED him to be elected. The grace of the office changed him into a Holy and Traditional Pope. The Powers that Be ( Masons, CIA, Jєωs) would not take that chance again with a valid conclave- and knew at that point that a true Pope had to be elected and pushed aside in order for their "will" to be accomplished with an unelected antipope. In 1958 the smoke changed from white to black to white again- unprecedented. And so Vll commenced and the rest is history. I believe that Siri was Pope until his death in 1989. I can't even imagine what they threatened Siri with , but many believe that it was a nuclear threat against millions of souls, including the bombing of the Vatican .
