Earlier today I noted that B'Toraso Shel R' Gedaliah has been removed from HebrewBooks.org, and I said that I presumed that this was as a result of protests by kannoim.
I was contacted by a representative of HebrewBooks.org who said that the removal of B'Toraso Shel R Gedaliah was not at the behest of kannoim who were bothered by its content, but rather because there were complaints that Rav Shilat's sefer was not authorized or approved by Rav Nadel's family. HebrewBooks does not want to get involved in complex rights issues and therefore removed the sefer.
I am glad that this was the reason, and I wish HebrewBooks continued success in their incredible work.

Meanwhile, if you missed downloading the sefer, I have another scan of it available here, with the approval of Rav Shilat.
