"projects" benefit. It's not that easy to declare that companies do honestly. We can infer that most VC's and founders don't think it does because everyone uses open source, but few (any?) of the major growth start-ups from the late 90's open source their key commercial code. I'm thinking of things like Facebook - they open source infrastructure as honey pots for engineers - but not their key code. That's also partially because the nature of how you made money changed - it became all about the data slurp.
