But there are capitalists that make money off Open Source or off Web 2.0:
IBM, for example,
makes Linux servers and mainframes, as well as offering applications and support. an IBM spokesperson told NewsFactor that the company invested $1 billion in its Linux operations last year, and said that by the end of 2001 it had recouped nearly all of its investment.

And today Israeli Internet portal Walla launched Wallapedia, a free Internet encyclopedia that draws its content from Wikipedia.
The more people need Wikipedia information the more they are exposed to Walla adds.
Money is such a strong and ancient concept that it refuses to be shares Web 2.0 style - it prefers staying in the hands of Web 1.0 close source capitalists.
