Ultima Ratio is exaggerating, as usual, but it is a fact that the fabricators of the Novus Ordo Mass toned down those parts of the mass that Protestants would object to most. One of the Protestants "observers" who helped fabricate the Novus Ordo explcitly admitted this. I'll get you a reference if you want it.
Mind you, none of this undermines the validity of the Novus Ordo. It does not make it "dangerous to the soul" as some hysterics believe. No, it just makes it a less complete expression of Catholic doctrine than the traditional mass. That's all.
This is widely known. If you don't know about this, you need to do a google search. Don't be lazy--get the information for yourself. There are even newpaper photos of the six advisors posing with Paul VI.
