Thanks for the update. There is no telling what these tech companies would do once they get hold of your computer. May be there is a fine print somewhere that allows them to collect some data in the guise of "learning" how to serve the customers better.
According to Adobe:
Do I need to be online to access my desktop apps?
No, the desktop applications in Creative Cloud, such as Photoshop and Illustrator, are installed directly on your computer. So, you don’t need an ongoing Internet connection to use them.
An Internet connection is required the first time you install and license your apps. But, you can use the apps in offline mode with a valid software license. The desktop apps attempt to validate your software licenses every 30 days.
Annual members can use the apps for up to 99 days in offline mode. Month-to-month members can use the software for up to 30 days in offline mode.
Go figure!
