Respect to Chamath! I am disappointed there hasn't been much discussion in the community around why AirBnB founders did this. Is @sama in support of this wheeling and dealing in general. I am pretty sure he is not. What is YC's official stand and ethos around cashing out by founders without providing the same kind of liquidity to employees. Since AirBnB has been successful beyond anyone's wildest imaginations this event was either forgotten or didn't really make for a bad PR. We don't need for things to fail spectacularly before we do what is right.
I see YC and YC community in general bringing more transparency and fairness to the way startups are built and run. They need to set the tone and tenor about what is right and acceptable. I am looking forward to see constructive debate around this topic in the comments (or not, if I am totally off the mark here).
