Google is getting away with this behavior because of their monopolistic behavior. If they had competition, they would be spending billions on customer support, but because they have a monopoly, they can get away with having virtually none. This is their way of saving money and taking advantage of their monopoly. It's a shadow version of monopolistic behavior where the absence of services can be done because we have no choice. We need to politicize this issue.
Facebook is exactly the same way.
When a company reaches such dominance, and when people completely rely on a company like we all rely on Google, Facebook, et al., then we need regulations to prevent what is happening right now, which is using their monopoly to make life easier for them by not spending any money on customer support.
IMHO trust busting would be lot more effective and free-market friendly than having some bureaucrats trying to write regulations for what counts as "adequate" customer service or not.
