Bp. Z has his reasons why he doesn't want to plaster everything all over the Internet, and intelligence/prudence has a lot to do with it.
You haven't lived the life of a Traditional bishop trying to build up the Church and preserve Tradition and the sacraments. There are challenges and obstacles you couldn't imagine -- ignorance is bliss.
It all seems so simple to you. A lot of us might THINK we know what to do, what should be done, like it's all cut-and-dried simple and easy. But it's easy to back-seat drive, Monday morning quarterback the situation, when you aren't involved yourself.
Strictly speaking, you (and others) have no clue what challenges Bp. Z faces on a daily basis.
Yes, people somehow believe that the clergy are required to broadcast everything from the rooftops ... and appeal to things needing to be made "public" and where they shouldn't be done "in secret" ... but the reality of it is that these calls are motivated by a feeling of being "left out", not being "in the inner circle" ... and just a general need to know related to what animates the vice of gossip, where they have "itchy ears".
+Willamson and +Vigano have been blasted for not publicizing his conditional consecration, and were denounced for keeping it "secret".
So, people also don't have the right definiton of "secret", since ... if anyone went and asked +Williamson, or +Faure, or Chazal (the 3 I've seen respond), they would all tell them, "yes, the conditoinal consecration occurred." See, that's not "secret". There never has been some requirement in Canon Law to post something on X or JewTube ... or, back in the day, in the newspaper, in order for it not to be "secret". Now, behind the Iron Curtain, bishops were often commanded to keep it REALLY secret, where nobody knew except the consecrator and consecrand. Bishop Williamson did keep a couple of his actually secret ... but only for a time.
There are prudential reasons why certain considerations would outweigh some fictional "right" that every busybody gossip on "CathInfo" has to know about certain things. Yes, if you are impacted, i.e. served by a priest who was ordained by, say, +Vigano ... then absolutely you have a right to know that +Vigano was conditionally consecrated, and I'm sure if that were the case, they would tell you. But why does Aunt Helen living on Podunk Iowa have ANY "need to know", much less "right" to know?
