First off, before Dolph accused me of dodging the arguments, as I said before you make a lot of sense in some practical areas. I agree that under the current law ISPs don't have much of a choice, which is why, in essence, I am arguing for a clarification of the law that would prevent misleading advertising. From what you've said I understand that you would support such a law/clarification.
I also agree that's it's very important for users to be notified regarding any sort of restrictions applied to them, and actually I would think a system where 2-3 warnings are sent before capping is applied would be even more effective at keeping "abuse" down without upsetting customers.
What I don't agree with, however, is your moral approach. I believe that it's up to the individual human being to make the distinction between right and wrong and legality can't always be "the end of". I do think it's wrong to cheat on your girlfriend and that's one of the reasons I never have/would.
Anyway, a discussion of "moral approaches" is way beyond the scope of this thread so I'll leave it at that
