You seem to be justifying their actions.
  There is no moral justification.

You can't simply assert that you are right and I am wrong. I gave you clear examples under which normal people can be influenced to do bad things. If you don't think that's possible, then cite errors in the evidence. But if you're going to simply ignore the evidence, I can't take your responses seriously. There's no point in continuing.

  because of this incident we can now clearly
  tell which companies are noble and which were
  pretending to be so.
  ...
  You admonish people for __bad__ behaviour because
  you care about preventing it in the future.

Humanity has been admonishing the immoral behavior companies/politicians/etc for millennia, and yet it still continues to this day. Appealing to morality does not work, has never worked, and never will work. Unless you fix the system, you are accomplishing nothing in the long run. What you're doing is the equivalent of blowing on a pot of boiling water to try and cool it off. Sure, it may get a degree or two colder for a few seconds. But unless you take the pot off the fire, the water will keep boiling.
