Because a search engine that almost always finds what you are looking for is a fruitful endeavor. A website that lets me keep up with my extended friend circle is a fruitful endeavor. A website full of educational videos (and yes, a lot of mindless entertainment) is a fruitful endeavor. By focusing on how they are funded, you're losing track of the fact that these companies provide incredibly valuable services.
