I don't know how I missed this earlier, but Mir using GPLv3 has created some
negative buzz: http://www.phoronix.com/scan.php?page=news_item&px=MTM5MjI
Here's a sample:
"Basically, Matthew explains how Canonical is trying to push Ubuntu (in the
form of Ubuntu Phone/Touch) into markets generally hostile towards the GPLv3
licensem since the license requires users be able to replace the GPLv3 code.
Android and other open-source mobile platforms tend to be under a more
liberal license that keeps open-source enthusiasts happy along with mobile
phone vendors.
With Canonical being the sole copyright holder to Mir (and other key
components), due to contributors signing the CLA, they are able to
exclusively relicense the code-base to their hardware partners and meet their
needs. However, this isn't exactly good for free software advocates."
