Nonetheless:
"Canonical, you are including proprietary software in Ubuntu's kernel and
expressly promoting it in some of your distribution channels. With this, you
are telling your users that you care more about convenience than their
freedom. How can you even claim to be "open source" in this way? Now, when
someone tells you you are subjecting your users to a license that could take
their freedom away at any moment, you do NOTHING for months on end. The
Ubuntu typeface is a beautiful font, but freedom comes before beauty."
