Here was the ruse perpetrated by Benedict XVI.
With the Indult, the Tridentine Mass was forbidden except where allowed by the Ordinary.
With the Motu, it was allowed except where forbidden by the Ordinary.
So with a little bit of semantics, Benedict XVI pretended to be the great champion and liberator of the Tridentine Mass. And many fell for this, considering him to be sympathetic with Tradition.
So that's why Father Kramer pines for the return of Benedict, despite the fact that his theology does not differ in any substantial way from that of Francis. Francis is just more bold and bumbling about it. Benedict was more subtle and can say things in typical modernist fashion, where it can be at once considered orthodox and heretical.
