I think having a publicly available history link that displays every TOS and Privacy Policy and the dates they were inforce isn't too much to ask. Maybe a last ten years thing is applicable (not retroactive). Users don't keep copies of the TOS they agreed to at the time of signup/registration as they expect it to be available from the service/corp/org. I think asking for a visible diff is asking for trouble, but being able to manually see how their TOS changed over time and how often it changes would be an objective way to ensure customers can make informed decisions, if they wanted to take the time. Edit: Available on request is a usability anti-pattern to deter consumption of information. I don't think it would be outrageous to require previously public legal documents to remain publicly available.
