What if I have an app, but don't want to pay for it?
Why are you not willing to pay?
I don't like the features.
If the app is useful, you should pay for it. If not, don't pay.
I don't want to pay for it since I can't cancel it freely.
Well, you should pay for something if you want to use it. If you're not going to use it, then just uninstall it.
