You honestly don't believe that, if the allegations are true, Heroku has done something wrong?
Inequitable money distribution aside, I think the bad press Heroku has received over this is probably enough punishment. I don't support how they handled this situation but the core problem isn't exactly that bad in the first place. Nobody died here, some companies simply had slow websites and to some degree that's their own fault, they should have done their own external monitoring if that sort of critical performance was that vital to them.
