Here’s some BSD and Linux comparisons that happened to come up recently:

First, NetBSD is moving to a 2-clause BSD license. Hubert Feyrer has mention of this, along with a small graph contrasting the word count of the GPL vs. the BSD license used in NetBSD, over time.

KernelTrap has a post up about a position statement from the Linux Foundation that “urge[s] vendors to adopt a policy of supporting their customers on Linux with open-source kernel code.” Compare that to the OpenBSD position on binary blobs.
