No, Ashkenazi Hebrew is not sooooo wrong and sefaradi hebrew soooo wrong.
I don`t know to whome you are referring your statement to.
But since our sages, mainly, Rav Saadia Gaon but also Rabbi Yaakov Emden, Rashi and the Ibn Ezra have been so kind as to explain to us how to pronounce hebrew, Why are we even having this discussion?
Just switch to the correct pronounciation. What's the problem?
And don't tell me, "I must continue doing whatever my father did."
That is a untenable position. Continuing a mistake just because your father did so ensures that nothing will ever be corrected.
That cannot be what G-d wants from us. Absolute fidelity to incorrect pronunciation.
it is difficult enough to switch from the Ivrit/modern hebrew/secular zionist pronounciation taught in modern orthodox schools and many shuls. Into our father`s ashkenazi or Sefaradi pronounciation.
But to change to a pronounciation that only Rabbi Bar Hayyim and his students know, that is just unfeasible. And if he is so sure, then he should write an article that proves it beyond any doubt. Proving not just that neither ashkenazi nor Sefaradi can be right. But proving that his pronounciation is right. And then that can be put to expert rabbis with different positions, and we can see the arguments against. And then we can decide what is correct.
First of all, he already wrote such an article. It was on his previous website. Torahlight.com but he shut down that site and did not carry the article over to machon shilo.
But I would suggest that you read the perush of Rabbi Saadia Gaon to the Sefer Yetzirah in which he says that hebrew and arabic are identical except for the fact that Hebrew has no J sound, no palatial D and no Palatial DH and Arabic has no P, no G and no V.
Otherwise the consonants are identical.
Therefore let's take a look and the Hebrew and Arab Alphabets so that we figure out the identical letters.
The most common Abjad sequence is (from left to right):
أ ب ج د ﻫ و ز ح ط ي ك ل م ن س ع ف ص ق ر ش ت ث خ ذ ض ظ غ
This is pretty much identical to the sequence in Hebrew alphabet but the Alphabet that is completely identical to the Hebrew Alphabet is the Aramaic Alphabet. Take alook.

As any of you can see this is identical to Hebrew.
After all, Part of the Tanakh was written in Aramaic so an identical alphabet makes perfect sense.
So the matter is actually quite simple. Listen to an Arabic or Aramaic speaker pronounce a Sadi and you will see how to pronounce it.
This is quite simple. The correct way to pronounce the consonants is well known.
The vowels are a little harder, but knowable.
Every single Jewish community pronounces a Hiriq and a Shva and Patah and a Shubuk the same.
I am choosing to not including the Polish and Hungarian for consideration because it so wildly incorrect.
The only vowels that are contested are segol, tsere, Kametz and Holem.
Rabbi Yaakov Emden says clearly that Sefardim are incorrect in pronouncing a Kametz and a Patah and in pronouncing a Tsere and a segol the same so the question is how do these nekudot differ.
Are the ashkenazim correct in pronouncing a tzere and ay?
Of course not. How why in the world would a yudh be continually added to words whose nikud is a tzere. It makes no sense. The yudh would be redundant if you are supposed to pronounce it as an ay. the Same goes for the CHoylem that ashkenazim say oy instead of o. It make no sense. One can safely say that tzere and holem should be pronounced the way sefaradim do.
Therefore, how is a segol different from a tzere?
Rashi calls a segol a patah katan. a small A sound.
Therefore the yementie way of prouncing segol like the a in rat cat bad and mad makes perfect sense and should be followed.
Now the Kametz. Well, we know that it must be different from a patah and the yemenite and ashkenazi kametz is the same so we should pronounce it like the a in father.
