They deserve blame for initiating the destruction of someone's life (jail time and fines in the millions) and not doing anything to stop it like JSTOR did. Yes not everyone commits suicide when their life is in ruins, but a lot of people do.
Even if Aaron was still alive, the things MIT did would be no less wrong, so let's bring the focus back to that.
I have no problems with not calling MIT "murderers". It's just that your post sounds like yet another blame the victim argument and it distracts people from the main problem of MIT screwing up and not being responsible about it. They are doing everything they can to try to deflect blame and hide wrongdoing. Their findings report was just a CYA document released on a day that's guaranteed to make it forgotten. It also doesn't help that they're blocking FOIA requests.
MIT could have stopped of all this by doing what JSTOR did.
