Use NLP for terms and conditions?

Just now listening to a podcast interviewing Brain Acton, the founder of Whatsapp, and he was a strong believer in privacy with his Signal foundation and Signal messaging app (Transcript below)

I was wondering for all those terms and conditions out there, is there a way to use NLP to help people understand what they are getting into and maybe possibly a rating system of terms and condition? So people can just copy and paste the terms and condition and advise people on what they are getting into.

That’s an interesting idea, but how will you train the model?

PS: reminds me of Asimov’s Foundation, when they submit the Anacreon vs. Empire contract to a computer, and the algorithm concludes that the contract actually contains zero obligation between the two parties.

This seems somewhat related?
