Thanks. I've been using them literally for decades. This one is a deliberate stylistic alteration, where a comma would have been the obvious choice, intended to suggest a specific speaking cadence.
Your source directly refutes your argument:
> In the 38-page lawsuit, xAI — whose AI model chatbot and image generator Grok is available on the social media platform known as X, formerly Twitter, and elsewhere — said it does not contest the state’s interest in banning the distribution of AI-generated nude images of real people without their consent. But it said Minnesota’s law “extends far beyond that goal,” banning many constitutionally protected images and video and subjecting the company to a penalty of $500,000 per violation.
