The author and their friend are in the thread so I'll try to not be mean.
Caveat: I'm Greek so a kind of natural amateur historian. That is to say I grew up reading about the prehistory and ancient history of Greece, as one does when one is born Greek and a geek. I've seen the Phaistos disk and linear A inscriptions with mine own eyes in Greek museums and I have dreamed of the day they would be translated. I am not at all unsympathetic to the hopes of a Linear A decipherement.
However. The claimed decipherment has all the hallmarks of imaginative and fanciful attempts to draw parallels between historical events and entities, that were not really connected, many of them notably inspired by the Hebrew bible. For example, remember when the lost tribes of Israel turned out in the New World [1]? Or how Biblical Sodom was actually destroyed by a comet [2]? Or the time that Venus was ejected from Jupiter and caused the Biblical Cataclysm [3]? Or, for less biblical but no less foundational texts of the Western literary canon, remember when Heinrich Schliemann discovered the Jewels of Helen of Troy [4] and the Death Mask of King Agamemnon [5]?
Or of course we could recall any of the claims to decipher the Phaistos Disk [6] or the Dropa Disks from Bayan Kara-Ula [7], and so on I'm sure.
All of the above is not to say that a decipherement is impossible. What it is to say is that it currently isn't possible; because we have no idea what the language that Linear A transcribes even is. It's not like the Minoan language is still spoken today in some far-evolved form, as was the case for e.g. Egyptian or Mayan or indeed ancient Greek [8]. So we have an unknown script, writing an unknown language, and to make matters worse there are no parallel texts with another ancient language that might help us bridge the gap. What there is, is some rudimentary understanding of the more obvious contents of Linear A texts (mostly, lists of goods) and the fact that some Linear A symbols have been reused in Linear B.
But, how were they reused? And what good is that knowledge without knowing anything about the language transcribed by Linear A? I can read German, a language that I don't speak, because I can read Latin script, but the meaning of the script might as well be Greek to me [9].
I'm a computer scientists, I guess, these days [10]. The problem of deciphering Linear A, or the Phaistos Disk, or any other script (that may not even be a script) that transliterates a language that we don't know is a problem of reconstructing information that we don't have, from other information that we don't have. I'm not saying it's completely impossible. I mean, who knows? Maybe we're just missing the right maths. But, what we're really trying to do here is de-noise a message garbled by the passage of time without even a guess as to the language the message is written in. Claude Shannon would tell you that it's a fantasy that is not worth pursuing. You don't have to ask him, you can just read his magnum opus [11] and check out Section 3 titled "The Series of Approximations to English" for an idea of what the mechanics of deciphering a script when the language is known look like with the only technology we have that can do the job reliably.
When Turing and the other Brits at Bletchley Park cracked the Enigma code, they at least knew it was, ultimately, a coded form of German. We may have a lot more compute now, and much more advanced tech overall, but there are some barriers that you cannot physically cross, no matter what resources you have. For example, you can't go faster than light and you can't escape the event horizon of a black hole. In the same way you can't translate text written in an unknown script, encoding an unknown language, without any parallel texts with a known language. There is just not enough information to do the job. Worse, if you try, you can endlessly come up with plausible "translations" and convince yourself that you have the right one, but you have no way to know you do.
I'm sorry but this claim is just a wild guess trying to link Hebrew to Linear A, without any serious evidence that the two are linked and without any evidence that the link is real, other than "look, I can guess what all the texts say!".

[8] I can read ancient Greek. The further back in time it goes, the harder it gets to understand what it means but I can still read the script. It has changed in 5000 years but not enough that I can't read it. Nothing like that ability survived for Linear A. I blame Thera.
[9] Except of course then I would understand it. But it's just German to me.
[10] I can assure you that took me by surprised, first of all.
