Issues for Mir using the GPLv3 license

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."
