Yes, yes, that’s the way to censor a sefer – that was written long before you or I were born. “It must be someone with an agenda.” “It can’t be glach if it doesn’t fit my worldview.”… Like many sforim, it didn’t come to us in 100% pristine and complete form. The editor who is the namesake of the Vilna Gaon’s father and is a descendant, had a significant kaboloh, and it impressed the talmidei chachomim who wrote haskomos for him.
In fact R’ Binyomin Rivlin, who was the father of R’ Hillel of Shklov who wrote the (original and complete) sefer Kol Hator, was also influenced by his cousin the Gaon regarding issues of the geuloh and he spoke about them, and these sources are distinct from Kol Hator. In any case the mid-60’s edition of the sefer had haskomos from the leadership at Ponevitch and some of the editors of Rav Dessler’s work Michtov Me’eliyohu. R’ Shlomo Zalman Rivlin who is apparently the source of some controversy for his attempt to publish the sefer (not backed by some propaganda machine, but very slowly, in small quantities, because he was a singular talmid chochom and a beloved chazan with few resources), was no lackey for anyone with an agenda.
