The FreeBSD Core Team took a look at the APSL a while back, and decided
that similar to LGPL/GPL, it was an acceptable license for use in
userspace for stand-alone tools, but that similar protections to LGPL/GPL
would be required for kernel code (not built by default, carefully marked,
etc).  That said, Apple tends to release only code they've heavily
rewritten or created from scratch under APSL; code they modify tends to
remain under the existing license (CMU, BSD, etc).  Generally they're
careful to label the license on the download page.
