Also, according to that link, section 3.2f is:

“You will not, directly or indirectly, commit any act intended to interfere with the Apple Software or Services, the intent of this Agreement, or Apple’s business practices including, but not limited to, taking actions that may hinder the performance or intended use of the App Store, B2B Program, or the Program.”
