Maybe it didn't take millions of people to build those things, but it did take millions of people to create an environment in which building those things could be considered a productive use of time.

The people who built Linux and Wikipedia didn't build it just for themselves, and indeed neither Linux nor Wikipedia would survive (in their current form) if they were not useful to millions of people.
