Well, it's not just tech; it's any large corporation that gets coverage. Some people can only hear "we're making the world better" so much when by all appearances they are just making their own world better. I know it's not a fair assumption to make, but look at what gets reported (billion dollar companies that produce nothing with no profits, high level executives greatly rewarded for failure, and so on) versus the unknown companies that actually are trying to make things better with no coverage.
