Again you start by asserting a contraposition. sigh. If you look at the question without assuming that contraposition exists, you will resolve most of your difficulties. That's what Müller meant by looking at it objectively imo.

"Müller Is the Pope's doctrinal voice, he cannot speak on this issue against the Pope, he has to support him or else resign." And yet you say he has spoken against the Pope on this? (technically you've said FOR the 4 cardinals). My only claim here is that Müller supports and always has supported the Pope and the teaching in AL.
Among the 4 cardinals there has been at least talk of speaking against the Pope on this issue, of "correcting" the Pope. Are they resigning?

I don't see the proposed alterations as particularly relevant. If I knew what they said, it might be. Otherwise it is just the normal operating procedure.
