I am on Fr. Feeney's side. He never was excommunicated. He was told by lawyers to not go to the Holy See unless they spelled out why he was to go, reasons. Reasons were never given. It was questionable if Pope Pius the XII had communication for all the mess going on in the Holy See. I really believe that Fr. Feeney was in a hot bed of bad jesuits in the colleges and I certainly can see Jєωs behind it.
I read that as of March 4, 2020, Pope Pius XII archives (secret?)will be opened for review.
