Several years ago, the Vatican said the exact opposite and even declared that it would be permissible for the faithful to financially support the Society.

The Conciliar church has absolutely no stability.  Even its own rulings are constantly subject to change based on changing situations.  Clearly, this change was deemed necessary to put additional pressure on Bishop Fellay to accept the deal--and, apparently, it worked (or, more likely, was part of an overall strategy).

After the reconciliation, I guess they can start working on changing the TLM.

PCED: Mass at SSPX Affiliated Chapel Does Not Fulfill Sunday Obligation

PCED (Pontifical Commission Ecclesia Dei) is no friend of tradition.  

PCED was Pope John Paul II's invention of the late 80s, set up a day or two after the excommunication of +ABL and the 4 Bishops for a specific purpose - -  so that the fox can guard the hen house. That is what the role of PCED has always been and will be until, if it were possible, the true faith as confirmed through tradition is completely obliterated. Once that objective is reached (if that were possible) PCED would have completed it's purpose and would exist no more.

PCED is simply another tool in the modernist's tool box used to Divide and Conquer.
