If Adobe wants to bring flexibility then they can use the rent-to-own model. Pay the monthly and when you've paid the full price, it's yours, fully activated forever. People who want to stay on the subscription treadmill can do so.

People are going to disagree on security, privacy etc. Some of it may be generstional, some may conceivably be the way our brains are wired. Read up on the latest research on authoritarian personalities, relative size of the amygdala, vs. the anterior cingulate etc. It may be that certain people are more inclined by their neuro-anatomy to be more fearful or more open to novel situations etc. It's early days yet but it would explain the huge and persistent disagreements in society. I wouldn't go so far as to suggest it explaind why some people embrace the cloud concept although it is a form of centralized control. Certainly would explain differing views on security vs. individual liberty/privacy etc. I think.
