When, say, IBM contributed a lot of stuff into the Linux kernel in early 2000s, that stuff became immediately available to anyone. Whatever cool stuff Nintendo or Sony may introduce in their versions of BSD kernels, we don't even know, let alone seeing them contribute it back. GPL works similarly to a patent pool: every participant sees that openly contributing to the pool is more profitable than being a renegade, as long as everyone else plays by the rules, too. MIT/BSD, while as open as possible, can easily promote a trade-secret type of environment, where any enhancements are never heard of, except under an NDA, and perish if their creators go under or lose interest. |
