Another key detail is that the experiment was carried out without having been submitted to or reviewed by the IRB.
The only traceable bad patch that can be traced to the university was for one student that tried to coerce its way to patch acceptance, by invoking slander and accusing of other kind of despicable behavior from the reviewer. Which ignited the whole drama (although it started way before that, said student didn't help with the already delicate situation and gave public awareness to the drama).
