About ten years ago, a very popular ICK priest was convicted and imprisoned for molesting altar boys in LaCrosse, WI. Yes, Mr Steven, these aberrations are found within Ecclesia Dei groups too.
I know about this priest.
He had a reputation for being the holiest priest in the Institute of Christ the King. My mom thought he was a saint!
I met him during a "Vocational Awareness" gathering for 3 days in the Wisconsin countryside. The boys there were ages 13-23, and at some point during the 3 days each boy got to speak with Fr. one-on-one.
Incidentally, this is where I met my first "big/rural Catholic families". (My old independent chapel only had 1 family with over 5 children.) The children from these families impressed me so much that I'll never forget it. They were polite, well-educated, etc. Before then, I had never met a 16 year old who knew so many dates and facts about the cινιℓ ωαr. They were all pro-Confederate (yes, this was in rural Wisconsin).
Anyhow, back to the priest in question. When I got to speak with him, I of course thought we were on the same side (we're both "traditional", right?) so I innocently brought up some things I was taught as a kid (I grew up Trad), such as the idea that the Novus Ordo was the "abomination of desolation standing in the holy place". Of course that was from Fr. Wathen's book, "The Great Sacrilege", but I didn't know that. I got it from Thomas A. Nelson when he taught my catechism class.
Anyhow, Fr. reacted strongly when I brought that up. He became angry and said, "Baloney!".
During this gathering, I also learned first-hand what "indult" meant. It meant helping out with moving the table to/from the Sanctuary to switch a church from Tridentine to Novus Ordo setup, and back again. We moved decorations, candlesticks, etc. It felt like Holy Thursday ("stripping of the altars").
I think every Trad should have to do this a few times -- it makes it very apparent how "un-sacred" the Novus Ordo Mass is, and what a compromise the Indult is. At the time, it shocked me because I thought the ICK was completely traditional. But my experience was skewed -- in my hometown, the ICK got control of an old Church building downtown, which they turned into a fully thriving 1950's parish. If THAT were the Indult, it wouldn't be as problematic (though it would still have problems). But not every Indult location gets its own exclusive church building.
