You would have to return to definition for 'freedom of speech'. There is a good chance that somebody may have very different concept of what it means.
Someone can consider banning hateful speech as activity towards 'more' freedom of speech. I do not subscribe to this, but be aware that a lot of people are not willing to admit they are against freedom of speech, so they redefine the term.
Further. It is "Free Expression Award". So there is even no gymanstics required in definitions. "Free expression" is something that anybody can define any way as there is no contesting an idea that is not commonly recognized.
