They misinterpret the document, though it’s been a long time since I looked into this stuff so you should probably do your own research.
Basically,
the Mass has been changed, many times, between the Council of Trent and Vatican II. The Novus Ordo Mass is still the Mass propagated by Trent - just changed significantly, which is within the right of the Church. .
The
canon of the Mass didn’t change between Trent and Vatican II. In fact, the canon remained unchanged from the time of St. Gregory the Great until 1962, when John XXIII added the name of St. Joseph.
Catholic Encyclopedia:
History of the canon
Since the seventh century our Canon has remained unchanged. It is to St. Gregory I (590-604) the great organiser of all the Roman Liturgy, that tradition ascribes its final revision and arrangement. His reign then makes the best division in its history".

With the introduction of the Novus Ordo, not only the prayers and readings, but the canon of the Mass itself was changed.
In the book
Reform of the Roman Rite, Msgr Gamber questions whether Paul VI had the authority to make such a change. He presents, and then refutes, each of the arguments that can be brought forward to justify the actions of Paul VI. The end result is that Paul VI did not have the authority to do what he did.
And what is interesting is that Cardinal Ratzinger (now Pope Benedict XVI) wrote the forward to the French edition of that book.
This is what Cardinal Ratzinger said about the New Mass of Paul VI in the forward:
Cardinal Ratzinger: “What happened after the Council was altogether different: instead of a liturgy fruit of continuous development, a fabricated liturgy was put in its place. A living growing process was abandoned and the fabrication started. There was no further wish to continue the organic evolution and maturation of the living being throughout the centuries and they were replaced – as if in a technical production – by a fabrication, a banal on-the-spot product”.
It is interesting to compare the above quote from Cardinal Ratzinger, to the following quote from Cardinal Ratzinger:
Cardinal Ratzinger: “After the Second Vatican Council, the impression arose that the pope really could do anything in liturgical matters, especially if he were acting on the mandate of an ecumenical council. Eventually, the idea of the givenness of the liturgy, the fact that one cannot do with it what one will, faded from the public consciousness of the West. In fact, the First Vatican Council had in no way defined the pope as an absolute monarch. On the contrary, it presented him as the guarantor of obedience to the revealed Word.
The pope’s authority is bound to the Tradition of faith, and that also applies to the liturgy. It is not “manufactured” by the authorities. Even the pope can only be a humble servant of its lawful development and abiding integrity and identity. …
The authority of the pope is not unlimited; it is at the service of Sacred Tradition.”
The Traditional Mass is a Mass the developed very gradually over the first centuries, before the canon was pretty much settled in the 7th century. The canon remained virtually unchanged until the 16th century when it was finally canonized. Then came the Novus Ordo where it was completely changed. As Cardinal Ratzinger said:
"There was no further wish to continue the organic evolution and maturation of the living being throughout the centuries and they were replaced – as if in a technical production – by a fabrication, a banal in-the-spot product.
