This contradicts the Catholic teaching, they believe that priesthood as a spiritial gift can't be revoked, but the Church can ban a priest to act like one as well as to wear priestly vestments.
They have broken their vows. They have repeatedly sinned and not only not repented but have bragged about their sins proclaimed them to the world. They have been a bad influence on young people. The have renounced and undermined church teaching.
They are not priests in the true sense of the world and should be defrocked and expelled from the priesthood.
