Part of the issue is that young fast-growth CEOs don't major on empathy, typically. It's somewhat contrary to the necessities of the job. These co-founders have absolutely no concept of how this woman feels, or if they do, they have determined that they won't let her know about it. The best thing say Paul Graham could do would be to hire them a crisis management coach, stat.
While the co-founders are reportedly worrying a bit about valuation right now, they could (and should) be turning this into an amazing PR story; massively over-compensating her, setting up a Lloyds-based insurance coverage program, appearing on something like Oprah to talk over how it felt, and what we can all do as we're moving into this awesome social-based home sharing..
