While you are right that ex-Grand Master Festing served with honour and is worthy of respect and thanks (which, by the way, he has been given), he also seems to have made some serious blunders in recent years. Including, of course, his final and recent blunder, of taking the Order into collision course with the Papacy. There was only going to be one outcome for him, from that mistake.
