Unity and Unity-2D uses Ubuntu logo

The Ubuntu logo is visible in the HUD start icon when Unity is installed by default. Not only would a Trisquel logo be preferable, but I may be correct in saying that the Ubuntu logo is trademarked. While this trademark may not necessarily impede the Trisquel GNU/Linux project's ability to use and redistribute the logo, the very fact that such a trademark exists is probably not in the spirit of Trisquel's commitment to free and libre software and content.

As per the Ubuntu Trademark & Copyright Policy:

"For example, when a user receives a computer with Ubuntu pre-installed, the system must not differ from a fresh installation with the standard Ubuntu image, unless the modifications have been provided, or approved and certified, by Canonical - or they are within the range of changes we allow as an Ubuntu Remix. When a virtual machine image is published or launched, it must also comply with this policy, so that the Ubuntu experience is consistent across different service providers. When a user of such a system or image updates that system, all the updates they receive must be consistent with the updates Canonical publishes to all other Ubuntu users."

Assigned as minor as this is obviously a minor issue.
