My main concern is being able to access files after I cancel my subscription. There may come a day when what I do for a living in no longer profitable. I would still like to look at my archived files, tweak them, add them to my portfolio etc... But not for $74.99.
I don't understand your concern - your files would still be local (just as they are today) - you do get cloud storage as an option as part of the subscription but it's not compulsory to use it and even if you did you'd just download all your files before you cancelled your subscription.
Of course, you would have to find something else to read the files (or save them in a different format), but that's about the only issue
