I don't care if Ortiz suffers an unjust end to her career. She'll still be alive. And I'm not suggesting the problem is that the action is too drastic. It's that the action sends the wrong message. The most likely outcome of Ortiz getting fired is that prosecutors are more cautious about bullying the well-connected; they'll judge each defendant on the likelihood of their martyrdom and act accordingly. It won't make defending oneself against federal charges any more cheap or accessible; it won't make a prosecutor approach you in a measured way. And the less powerful defendants are still going to get screwed--which is to say, those who
most need federal prosecutors to treat them reasonably and decently. Firing Ortiz (or, more accurately, Heymann) will just make others more cautious when dealing with the rich and the famous.
Prosecutors bully defendants into taking bad plea deals because they're judged on their conviction rate. People act according to their incentives, and federal prosecutors are incentivized to get quick, cheap convictions the way they do it now. You want change? Change the incentives. Crucifying one out of a hundred doesn't work.
