I don't think it's right to consider all tech giant products equally. You have to consider things like whether the product or service is a significant source of revenue relative to the company's overall business. For example, Google probably could've made Reader profitable, but it was not on track to be used by a billion people. Relative to Google's overall business, it was uninteresting to them. It might've been a great startup, though.
