That’s sort of his whole point. He’s basically saying that they are unaware of the respect according numerous times, and absurdly tampered with this one because they couldn’t stomach it.
But all the other times they could stomach when reprinting Tzemach Tzedek?
Basically what I think I'm trying to say is does the T"T actually reference the Gr"a multiple times bderech kavod as claimed?
If yes, it's strange that kehos could stomach all the other times and this one not because of their great "kvod rabbom"?
If no, then why is he saying the T"T did?
Either way the other version in the footnote seems more believable. But perhaps I am missing something and as noted I didn't read the whole footnote.
