For many, this distinction is more of either an academic one or one where we are OK with those kind of restrictions. Where I live if I did many of these things I would be either criminally or civilly (the right phrasing?) liable so having a license that tells me I can't break the law is a little redundant. I think 4 is possibly legal but an edge case and the last one is nation state level.
You are probably technically correct, but the context here is very important IMO.
7. Updates and Runtime Restrictions. To the maximum extent permitted by law, Licensor reserves the right to restrict (remotely or otherwise) usage of the Model in violation of this License, update the Model through electronic means, or modify the Output of the Model based on updates. *You shall undertake reasonable efforts to use the latest version of the Model.*
I think this means it is now illegal to use SD 1 if at all reasonably possible to use SD 2?
It does add risks for a company sure.
edit - thanks for adding that in, it's an important part of the picture.
This way if a court rules that generated models don't qualify for copyright they can still enforce it under contract law.
