Oreillynet.com has an article disputing a ZDNet column, which said that Apple isn't giving back to the Open Source community as much as it's taking. "Apple has given back exactly what was asked of them by the BSD community. Evan
is asking them to give back more than they have taken.
He wrongly asserts that they haven't given anything back. The Darwin project is an
open source project started by Apple to allow the source code for the project to be
available to the community. The code they have taken is made available via the
Darwin project. They also have paid developers working on the project, which in my
opinion is giving back to the community."
