How is it a win/win if I lose my data when I quit paying the subscription? Having proprietary data formats means that if I want to keep using what I've created, I'm kept hostage by my subscription. It's a lot better with things like Office, where other programs have been able to extract the data, but it still seems too much like extortion for my liking.
