I think the point that was missed here was that the idea wasn't the investment, investors invest in people. If one idea fails, the person is still capable of other ideas. If the failure was due to poor judgement, then the investor too, made a poor judgement, but there are many reasons why a startup, be it a tech startup or a restaurant might fail that are no "fault" of the management. Also investors are diversified, so while the startup failed, the portfolio as a whole might have still been up, so yet another reason why pg wouldn't get too upset.
