That is correct from a provider's point of view. "Whatever, read this all anew and leave if you can't be bothered to accept these new rules". However a lot of legal systems consider changes to an end user license agreement to be non binding if they are communicated in a hard to distinguish manner. Why would you force your end users to flesh out every tiny change, when you could communicate the changes much clearer without real extra effort. To avoid any discussion prudent EULA providers simply communicate changes in a track changes format, to prevent providing ammunition to lawyers defending a lazy end user.
