I have a theory about this, tangentially. The theory is probably wrong, but here it is. It may be that “traditionalists” disproportionately include people who are somewhat cranky. I don’t mean offense, truly. I count myself among them. Not cranks, but cranky. People who care a bit more about ideas than other people do. Perhaps people who are a bit too sensitive. These people become disporportionately offended at the changing of the rite. Or, they are among those least well served by the especially poor way the rite is carried out where they happen to live. So, cranky people go out looking for arguments and reasons, and ways out of what they see as a trap. They are irascible. There’s an easy way to recover: just realize, in faith, that the rites approved by the Church cannot fail to conduce to piety and cannot contain error. That re-squares the issues “infallibly”. But while a person is cranky, they may see anything incorrectly. Take the photos often passed about, mostly from the same archive(s). The one, above, of the teenagers, is not even a mass, but is compared to a view of the priests at the Tridentine rite: this is an irrational comparison without substance. Or the pictures of masses held in diverse locations: on a jeep hood, on a canoe, in a backyard: what of it? I would simply be grateful, if it were me at those masses, that Our Lord was coming to me in that place. Of the millions of masses celebrated yearly, only a tiny handful are in unusual locations. When a cranky person is in the process of being cranky, he doesn’t want to evaluate things rationally. He draws irrational comparisons that he thinks fit a pattern he has decided is applicable.
The interrupt to all that is: The rites approved by the Church are infallibly orthodox, avail unto salvation, and require your attendance.
We may assist at the Tridentine rite of mass, but what I have noticed is that there is an overwhelming tendency to want to judge the Pauline rite adversely, “novus ordinarians” afterwards, and finally to lapse into an erroneous ecclesiology. This is the path you are treading. It leads to a lack of charity, coarseness, a bunker mentality, the heresy of “traditionalism” in which people refuse to accept the Church’s magisterium, and to unnecessary divisions in the body of Christ.
