The art argument is solid as fuck. Obviously it's kinda ridiculous to call custom cake making art, but at the same time, it's exactly what it is. If you create something unique, it's art.

Not true. Twitter is a "public space" company, and they totally can pick and choose who their customers are. They can give me the boot for literally nothing, and I have no recourse. Pubs are called pubs because it's short for "public house". They can refuse to serve you for no reason, and at least in the UK, if you're asked to leave a pub for no reason, and you refuse, you are committing a crime, namely "trespass on a licenced premises". It's one of the few examples of trespass being a criminal offence in the UK, along with trespass on a railway, and on military property.
