Tl;dr - Traditional Catholicism isn't very profitable (spoken) and Westen's direction could have opened them up to a hostile workplace suit from some employees (implied).
Always follow the money.
It came down to money, traditional catholic mindset is not profitable, and lifesite is in enemy territory: CANADA, where the more left and satanic you are the better , i assure you, most of the money they raised came from the states
.
Anyways, Westen DID an awesome job, he should continue.
JHW could bring the Church back to Tradition but realizing that Vatican Council II and the Catechism of the Catholic Church when interpreted rationally are traditional. So he does not have to be labelled a Latin Mass traditionalist any more. Vatican Council II is an ally.
