You appear to have a very strange definition of "evidence", and it leads to slanderous accusations on your part.  What is your "evidence", since you present absolutely none in the rant that follows this statement?

Because he spent 14 years with Brother Natale?  It was right around the time that he left when the Dimond Brothers started to move toward sedevacantism, so something had change.  Bishpo Williamson spent decades with SSPX.  Did he change or did the SSPX change?  When there's a change, either on the person's part or the group's part, a departure under those conditions constitutes evidence of nothing.

For no reason at all you "firmly believe" Menzingern shut down CFN ... as if what they state as the reason isn't at all plausible.  They're not wrong about the fact that printed publications simply cannot survive financially anymore ... and they were simply unable to adapt by figuring out ways to monetize the operation without suscribers paying a monthly fee to receive the publication.

TD,

I think there's evidence the SSPX took over Fr. Gruner's trad publishing empire after he died.
Fr. Gruner owned the second largest printing company in Canada and kept full editorial control over CFN.

When Bp. Fellay celebrated Fr. Gruner's requiem Mass, this was the initial hint of this asset transfer.

I could go through a host of CFN articles before and after Fr. Gruner's death that displayed purposeful misdirection and SSPX propaganda.  Since the loss of true bishops in America, CFN carried an exaggerated amount of influence and leverage within the TLM movement. 

If I had time, I would research CFN back issues to give you links and article dates to prove my points.
But for time's sake, here are a few examples, off the top of my head:

1st example: John Vennari & Fr. Gruner spent a few episodes, both CFN articles and Fatima Center interviews debunking the Cardinal Siri coup d'etat.  They said it didn't happen... so it meant we must trust their holey analysis.

2nd example: Fr. Gruner knew there was a fake Sr. Lucy and he suppressed it so as not to alienate his novus ordo donors. He stated this in summer of 2009 to a casual group of Catholic men on the grounds of the Winona seminary at the SSPX ordinations.  He never ran this very important story in CFN.

3rd example: After Fr. Gruner's death, CFN was used to embellish and glorify the SSPX's history.  One such story was retelling the myth of Princess Pallavicini, as a bulwark of Europe's Black Nobility.  She endorsed +ABL's TLM movement and the SSPX started to gain momentum.  The big problem with that story is that the Pallavicini's are one of Europe's highest ranked mobster families.

4th example: I was paging through some CFN back issues around 2019 and came across a historical article on the Armenian genocide.  Well, in this pro-Jєωιѕн history, CFN (SSPX) was claiming how the jews suffered from the atrocity.
Anyone who knows any truth about the Armenian genocide knows this is Jєωιѕн propaganda.

Note: After the SSPX took the Jaihoff bribes in 2011, brokered by the jew lawyer, Maximilian Krah, they rebranded themselves.  Part of their new image was to be silent and sympathetic to Jєωιѕн interests.

Above this text is a very good letter...

Mr. Saglio obtained from the relatives of Bishop Lefebvre still alive, his brother Joseph, 96, and his sister Mrs. Marie-Thérèse Toulemonde, 85, a warm, very encouraging, even enthusiastic agreement, each understanding the good that these sermons can do to souls.

Of course, there was no contact made with the FSSPX. Since the death of Bishop Lefebvre, he(Saglio?) told himself that he had not left a will. The ESR therefore had no reason to ask for any permission from the FSSPX, Bishop Lefebvre's brother and sister naturally appearing as the only beneficiaries.

On March 25, the 20th anniversary of the death of Monsignor Lefebvre, the books (3 volumes) were available. Three days later (March 28) the FSSPX attacked, declaring that it had the exclusive rights of publication alone, and demanding that the ban on the dissemination of Bishop Lefebvre's sermons.

The ESRs, not at all intimidated, defended themselves, the property being absolutely not clear, and the censorship for 20 years of these sermons constituting a scandal that can be seen by anyone, especially since the few rare sermons broadcast by the FSSPX were censored on important passages.

The interim trial took place on Thursday, March 31.

What was the surprise to discover that he was blamed on the ESR and Mr. Saglio, positions that are those of the Church of always, the Holy Catholic Church, and which were those of Mgr Lefebvre[3].

This low blow is very serious.

This confirms to us that the FSSPX has betrayed its founder, that it has sided with the enemies of the Catholic name, and that it is ready for anything!

It's HUGE: censoring its founder! Betray its founder! Use the worst arguments of our enemies! Of course, they went through the camp of our worst enemies!

The FSSPX is dead, there is now only one ersatz left: the Fellaysienne fraternity!

They knew that their position on literary property was doubtful, so they attacked the person of Mr. Saglio, an old process well known to our enemies..."
