They simply could have committed not to becoming a publicly traded company. I know every YC investor looks at going public as the end all be all for every company on earth but I think the pursuit of the public market at all costs mindset typically espoused by communities like this one is morally devoid and obviously has long term consequences in the tech community at large.
Go public at all costs is the mindset here and in most VC communities. Make money at all costs is really what they mean to say. Get rid of that mindset.
Google used to have a moral compass. That was the Google I grew up with. Before all the pressures of being a publicly traded multibillion-dollar conglomerate got to them and now they are basically no better than ATT.
