Google, Youtube, Facebook, Twitter, Reddit were all magical. Digg was also magical but it died out when tried to scoop returns in inelegant way.
Rich people did not become rich and don't stay rich by giving money away. When Youtube was advertiser unfriendly it was magical but it was also burning a billion $ a quarter, the same goes for all those "evil" companies. It all was a scheme to create and grow a market up until they run out of people. When they run out of people, it's time to make the money back out of it. Hmm, maybe I should remove the " " of "evil" but I am not sure. What was the alternative? The French "internet" maybe, but it died if in the face of capital fuelled frenzy of the American internet.
BTW, that's why I am an Apple fanboy, I like the idea of directly paid services. The relationship is simpler.
