1) They did not hit stable. GKH is referring, in this email, to a legitimate attempt to contribute from a student at UMN. Whether or not this student was part of the hypocrite commits study, I don't know. But it's not a hypocrite commit, just a normal buggy commit. You can tell, because it's from a umn.edu email address, which they did not use for hypocrite commits.

2) I don't actually care about the internal policies of UMN's IRB. Whether or not the study's approval was proper and whether they would get into trouble with their boss is not my problem. The point is that what they did is obviously not immoral or unethical.
