There is a broader statement: open source is fueling the future. In fact, holding off projects close sourced only makes it profitable for one-party for a while, until an open version spins off. Open source copies are bound to happen.
Alternate theory: open source is destroying the future. In fact, significant progress is occurring from concentrated capital investments made by public entities or corporations, and development slows down or regresses once open source alternatives become available. The likelihood of open source piracy occurring decreases the overall desire for coordinated, large scale technology development.
