Making things up? Calling what the Pope says an "admission" is not making things up, in and of itself? As if the Pontiff had somehow previously denied this? Can you possibly be serious?
You really need to take that up with the author.
But Pope Benedict XVI's statement in his 2007 Summorum Pontificum that "the typical edition of the Roman Missal promulgated by Bl. John XXIII in 1962 was never abrogated" does sound to me like an admission that the traditionalists had been correct all along between 1969-2007, while the pontiffs had been silent on the matter.
