One thing I don't like about the subscription model is that if or when you decide to stop paying the subscription, you know longer have access to the software you "paid" for and you won't be able to open your files in older versions of software you may have bought such as CS6 (Photoshop, Illustrator, InDesign, Acrobat, etc.). Am I wrong with this assumption?
I think you would be able to open them in a legacy standalone program (or even something like PS Elements for PS files) but not all the the filters/adjustment layers/etc. would work properly. I guess in theory there should always be a stamped layer to at least have a full rendering of the file if you can't make further adjustments to it.
