What would she have done there? Would it simply have been time-filling for the sake of time-filling? It's a job, not a prison sentence.
I've been on a PIP. It was a place with an "up or out" mentality as a legit part of the business culture. The only mistake they had made was not being brutally honest about that when I'd gone there in the first place. And some of that was probably on me. You either went into essentially program management or out. I'd been looking for a job for about a year before I got laid off. It was disruptive, but it was for the best.
I could have gone for a Masters degree and possibly stayed, but towards what end? I'm already "overqualified" as it is. The logistics of that alone meant 120 mile round trips and there were actual financial risks involved.

I worked a few contracts after that and made some of the best networking contacts to date. This worked out just fine.
Maybe Netflix could have figured out a way to make it work, maybe not. You pays your money and you takes your chances. They took a way out and at least ended it. The only thing that is suspicious about the story is that she wasn't perceived to be of value to the new automation scheme ( which I presume is the legendary Chaos Monkey ).
