Accountability can take many forms. I don't think they should be fired for making a mistake, I think they should release a statement recognizing their failure along with a post-mortem. Not a particularly high bar, but most leadership failures are often swept under the rug without any public accountability or evidence that they've learned anything.

We have evidence of prior failures with livestreaming from Netflix. Were the same people responsible for that failure or do we have evidence of them having learned anything between events? If anything, I'd expect the best leaders would have a track record that includes failures while showcasing their ability to overcome and learn from those mistakes. But based on what information is publicly available, this doesn't seem to be the case in this situation.
