Hi, Nishan. This is the InDesign user-to-user forum, where users like you and me ask questions, and are mostly helped by other users. Sometimes someone from Adobe will look in on the forums, but it's mostly just people like us. I work for a company that has not yet upgraded to the cloud version of InDesign, but from what I've seen, there is a way to remove the software that is similar to the way it is installed. Sorry that I don't have specific info, but I thought you'd like to know that you aren't talking directly to Adobe here. Good luck.
Here's something I found with a quick Google search. See if this helps: Creative Cloud Help | Download, install, update, or uninstall apps
To avoid continuing to pay for the program you would need to go to your account at Adobe.com and cancel the subscription.
