The principal of being open source.

Facebook's BSD+Patent License is not open source.

That combination isn’t certified by the OSI. To be OSS, the software has to be licensed under an OSI-approved license, which it isn't.

So for WordPress to be including non-open source licensed software in core seems to be going against the grain, wouldn't you agree? Would that mean that WordPress is no longer open source?

Perhaps Facebook should submit their license for approval, then this would all go away?
