Both are to blame. Neither are to blame. Much of the success of Linux has been attributed to the GPL. It certainly had a role to play in opening up WRT firmware.<p>The truth is that the GPL is a pretty restrictive license. I don&#x27;t think it&#x27;s fair to blame anyone for the fact that it&#x27;s not compatible with much. That&#x27;s its defining feature and the main reason people choose it; so if it blocks ZoL, it&#x27;s working as intended.<p>Which I consider a great loss. ZFS is fantastic.<p>I use the BSD 2-clause license on my own stuff, but I can think of situations where I&#x27;d rather use GPL.
