Let's assume everything the guy in the video (the self-anointed journalist) says is true and that OpenAI is required to "hand over" those forms to anyone who asks...

With that said it still doesn't mean that if don't do that that you get to shove your way in (or try to) and start yelling at people lol.

I'm sure the actual process is that if they are required to do so and do not then you a member of the public ("data journalist" or otherwise) can pursue legal action. The "I'm entering the property NOW!" thing is likely not codified into whatever law this guy is quoting. "If they don't turn it over you're allowed to invade the corporate HQ!" Doubtful.
