Take Google, Facebook and Twitter, for example. Those companys’ consumers and customers are different populations. The consumers are the users. The customers are the advertisers. In fact, our consumption is what’s sold to advertisers. “If it’s free, then you’re the product,” the saying goes. It’s not exactly right, but it’s close enough to make some points, one of which is that your influence on those companies is far less than it would be if you were paying for services rather than merely using (or consuming) them.
