@lightweight They just don't.

They plaster lots of "terms of service" in many different places, but they don't version them or record their differences, so indeed you can't feasibly know which terms you "agree" to.

Really, I haven't seen any "terms of service" from the sort that are fair contracts, plus the suckers (usually) haven't signed them either - so even the suckers arguably haven't agreed to the terms, although the legal system is on the side of businesses and not the suckers.


Such "Terms of services" are yet another one of the proprietary tricks that assists with pulling things off that aren't even legally permitted.
