It's possible but unlikely.

MPL, for folks who aren't aware, is a successor to the CDDL seen in Solaris etc. and is a per-file copyleft, thus having a nicer legal structure while getting the same rough benefits of GPL or at least LGPL. The idea is “any modifications to this file must also be open-sourced under MPL, but you can package this file with proprietary other files that are not MPL and integrate them into a larger proprietary thing as long as your modifications to this file alone are open-sourced.” The goal is to protect weakly from Microsoft-esque “embrace, extend, extinguish” as GPL does but enable commercial integration the way BSD does.

In practice nobody seems to be all that pissed at Mozilla because of their license; the MPLv2 added GPL compatibility so the GPLers are mostly able to use MPL software and it gives a nod towards the stronger copyleft they like; commercial applications which just use the software as a library don't mind.

Minor historical nitpick: The CDDL was based on the MPL. There used to be a lot of licenses that were pretty much the MPL with the names changed.

Thanks, I appreciate the correction!
