According to Robert Moynihan (Inside the Vatican), here is a possible motive for de Mattei's slander:

“The question we pose is therefore this: analysis of the language and content of the docuмents produced by Archbishop Viganò during the years 2020-2021 reveals an author different from that of the years 2018-2019. But if Archbishop Viganò is not the author of his writings, who now is filling in his words, and perhaps even his thoughts? We would never have opened the case if so many good traditionalists were not presenting as a quasi-magisterium the statements, not of Archbishop Viganò, but of his ‘double.‘” —Italian professor Dr. Roberto De Mattei, June 21, in an article published on his website, Corrispondenza Romana (

link to an English translation; the full text is also below)
Dr. De Mattei — a leading, generally conservative Catholic intellectual in Italy who has been a friend of Archbishop Viganò for many years — made a startling allegation two days ago which has gone viral.
That there are “two Viganòs.”
***
De Mattei accused Viganò of having a “double,” a “stand-in,” a kind of “false Viganò” who — and this is De Mattei’s central allegation — has written many of the “Viganò letters” over the past year or so which Viganò has signed.(!)
De Mattei says at the end of his essay that Viganò was contacted privately and confronted with this allegation.
Evidently, Viganò assured De Mattei that there was no truth to the allegation.
***
Why then has Dr. De Mattei issued this public accusation, if Viganò already told him (as it appears) that it is not true?
***
Evidently, because the matters that Viganò has been touching on in the past year (the “global reset,” the national lσcкdσωns, the virus, the various vaccinations, all such social and political matters, but also the archbishop’s increasing focus on the beauty and holiness of the old Mass, and his tracing of a certain rejection of traditional Catholic teaching (which might be termed “modernism”) back to the 1960s, and before, rather than seeing it only in the years of this present pontificate) are very disturbing to some — more disturbing than Viganò’s revelations of corruption and coverup in the Roman Curia, which were the main burden of Viganò’s early letters, and which never provoked the suggestion that Viganò had a double.
In other words, as is often popularly said, “When you are over the target, the anti-aircraft fire intensifies.”
Viganó has touched a nerve, and one of his old friends has now placed in the public domain an article which will inevitably leave a trace of doubt, because many will say, “Well, some think there are two Viganò’s…”
In this sense, a certain damage has been done to the archbishop’s reputation and credibility by the public circulation of this allegation.
So again, why?
Part of the answer may lie in the fact that a few weeks ago Dr. De Mattei — as Viganò notes in his response to the accusation below — came out in support of the worldwide use of the presently available emergency injections (called “vaccinations” though they are not ναccιnєs) as a way of stemming the pandemic. (

link).
De Mattei contended that such use was moral even if the injected material was in some way derived from the use of aborted fetal tissue, something Archbishop Viganò has repeatedly denounced as immoral.
De Mattei asked: “1) Is it morally licit to use ναccιnєs against CÖVÌD-19 that use cellular lines coming from aborted fetuses?” And he answered: “There is… a reply that is more easily accessible for the Catholic with good sense, and this is it: it is licit to be ναccιnαted [even if the ναccιnє is derived from the cells of aborted human fetuses] because the Church assures of this, through its most authoritative doctrinal body, the Congregation for the Doctrine of the Faith.”
It is in that moment that the first “rift” between the position of Dr. De Mattei diverged from the position of Archbishop Viganò.
