@rahmu: The thing you're trying to disprove is called open source!
Wrong!
It's foolish to think that open source holds on good will and ideals. There's a shit ton of money involved, personal interests, profitability and general selfishness going around. I had
already attempted at covering that before.
Open Source is based on the idea that it produces
better softwares. There exists a separate community called the Free Software community, that fights for a Greater Good with strong anti-corporatism, but it's considerably smaller and not nearly as influential.
Open Source is not as good as its worst contributor. I can manage to get a patch in the Apache project, maybe. But it won't affect the global quality of the product. The idea about being as good as your weakest link gets diluted in the mass of really large projects.
Bottom line, if there weren't commercial interests in it, Open Source wouldn't exist. Historically, Open Source was a term invented by a major subset of the then-only Free Software community, precisely in order to attract venture capital and money.
