You suggest that the institutions that have books that need to be hidden is the exception. I challenge that. No, I do not have inside information. But we observed the past few years with much discussion about the Markey bill which would open yeshivos to lawsuits about alleged abuse, with the knee jerk reaction that all of our yeshivos would be implicated and either forced into bankruptcy or closed. Really? Are they all guilty? Well, maybe not all, but a noticeable majority maybe. Seems the matzav of free of aveiroh is not universal or even close to that.
As for airing this publicly, I commend you for not using the “chilul Hashem” line. It denigrates the concept to refer to publicity only. My Pirkei Avos says: כל המחלל שם שמים בסתר נפרעים ממנו בגלוי. So chilul Hashem refers to behavior inconsistent with the value system, and whether in secret or not remains as chilul Hashem.
Lastly, “check the place out” and “ask good questions” sounds nice, but it is actually comical. The thief that gets caught is the one that tells others about the heist. No menahel or administrator will disclose the shady stuff going on. It is undercover, so checking won’t find it. And those protecting the operation will never admit to it until arrested and facing a judge (and then, maybe).
