What is the point of month to month plan. Annual contract, paid monthly is cheaper. Even If you need Cretive Cloud for a month, then you can cancel Annual contract any time and pay less. Where is the catch?
Annual plans require a 12 month commitment. And your rate is guaranteed for the entire year.
Month-to-month plans do not require any commitment. You can cancel anytime without incurring a penalty fee -- good for people who only need the app for 1-3 month projects. But the rate is subject to increase.
Different plans for different users.
