Creative Cloud is a subscription service. You do not actually own the software, Adobe licenses you to use it. It's rather like subscribing to a newspaper. As long as you pay, you get it delivered. You stop paying for the subscription, it isn't delivered any more.
You do not have to "ask permission" every time you use a program. You do need to log in to activate the software on your computer. You do need to have an active internet connection at least once every 30 days so that your license to use the software can be verified. This is an anti-piracy measure.
