Unilateral changes with little or no notice
You are agreeing that Apple can change these rules anytime and your continued use means you accept the new version.
“Apple reserves the right at any time to modify this Agreement... Your continued use of the Services will be deemed acceptance thereof.”
What that means: You may accept unfavorable rule changes without explicitly clicking 'I Agree' again.
Apple can change the terms whenever it wants, and simply keeping your account active counts as accepting those new changes.
