To his credit, Vigano avoids the question of "vacancy" as a distraction: ...

It's not a distraction, as we have lots of erstwhile Catholics losing the faith and sliding into Old Catholicism by attributing this destruction to papal authority, attributing corruption to the Magisterium and the Church's public worship.

Most eminent theologians believed even a manifestly heretical pope would retain jurisdiction over the Church until deposed, and I presume from this letter this is Viganò’s position.

You also need to read up on the “authentic magisterium,” which can err.

That has nothing to do with the issue at hand, where you believe in the heresy that the Magisterium of the Church and the Public Worship of the Church can become corrupt, harmful to souls, offensive to God.  However you want to explain it, these things did not emanate from the legitimate papal authority that was freely exercised.

You will be judged by God for attempting to spread your blasphemy and heresy against the Catholic Church.

And you're also lying that "MOST" theologians believe the Cajetan opinion.  Majority opinion was always for the actual Bellarmine opinion (not S&S pathetic reinterpretation of it), and the opinion was almost entirely abandoned after Vatican I.

Father Chazal has a different understanding of the Cajetan / John of St. Thomas opinion as well, where he says that these impounded popes lose all authority, and yet you refuse to accept that lifeline to avoid heresy and blasphemy but you persist in your bad will in them ... your absurd distortion of the notion that heretics retain jurisdiction to validly absolve in the Sacrament of Confession notwithstanding.

You have show yourself to be of incredibly bad will against Holy Mother Church, whether out of arrogance or due to some psychological problem, throwing the Church under the proverbial bus so you can be comforted by the thought of this tyrannical heretic walking around in Rome wearing a white cassock being the pope.  To save Bergoglio, you're willing to sacrifice the Church.

Archbishop Lefebvre clearly taught that this degree of destruction is not possible given the guidance of the Holy Spirit over the papacy; he merely refrained from deciding on what the explanation for it was, maintaining that SVism is in fact a possibility.  While claiming to be most faithful to the Archbishop, you reject his position on the matter also.
