Would the nuance of the sentence changed, if I say "It's all about freedom" instead?

Yes, the nuance would change slightly if you said "it's all about freedom" instead of just "it's about freedom". "It's all about freedom" implies that there is nothing else that it could be about but freedom, so adding the "all" makes the sentence a bit more exclusive. However, it does not change the overall meaning.
