We currently are using Trademark brands of Twitter, YouTube and
Facebook (and others on Ubuntu.com mobile area) all outside of the
scope of each individual services Trademark policy... This is
something that needs to be addressed especially since some of the
words are also protected under copyright law and we are purporting to
be releasing the core apps under the GPL which would raise a major
conflict with the license.
See below:
Don't use Twitter in the name of your website, application or product.
