Apparitions are thoroughly investigated by the Vatican before they are approved. And they must cease before any judgment can be made at all.
I see no problem with sorting out all the details. If you are on the inside track here, please let us know. Otherwise, I believe it’s been thoroughly investigated. Have you read any of the books about Fatima?
Do you even know the names of the three children?
An alternate deity, an alternate focus of worship and adoration, an alternate source of revelation, an alternate channel for accessing transcendent reality with our prayers -- and you don't smell a rat?
Perhaps, the issue at stake here is the authority of Rome. This is a loyalty test. Those who humble their necks beneath the yoke of the papacy prove the sincerity of their submission by embracing something they should know to be ridiculous.
I've studied cults for a few decades, now, and what I see in the cult of the BVM is demonic. Tarted up in religious verbiage and weasel words, but ultimately channeling human fealty away from God and towards one who desperately wants it -- and wants it badly enough to accept it while wearing a mask. Then, perhaps "at the hour of our death," when it's too late, the mask slips off ... and the Marian devotee falls into the embrace of that luminous angel, Lucifer.
