One could also ask why anyone should be working for military contractors/armaments manufacturers/small arms/weapon manufacturers/industries of adverse environmental impact? I think the ethical hazard in working at these places are more serious, than Facebook, which is after all a non mandatory, non essential service, which most of its users use for idle pastime. I do however why such questions are being asked of Facebook/Google and not of companies like Thales/Lockheed Martin? Perhaps the mainstream media feel more threatened by Facebook/Google, because like all the MSM crave power, and Google /Facebook /other social networks can democratize dissemination of opinions and erode the power of MSMs to act as gatekeepers of Ideas.
