Name hope vs. islands law

Just trying to understand bias of the variations.

There are speculations that the antichrist produced the Masoretic text to
remove prophecies about our Lord Jesus Christ. It is logical but no
proof. Also, the antichrist is hiding the Dead Sea Scrolls from public view,
logically admitted, because of exposure of their tampering of the Masoretic text.

Second speculations that Zorba changed Septuagint to fit Greek NT.
Also logical, especially taking into account many corrupted Greek NT versions.
But this speculation is also without any proof.

Now, what is point for Samaritan Pentateuch to be altered? I do not see logic here.
They preserved even old Canaanite letters that means that they took great care
about the text.
