@chrisoliver@indieweb.social @pluralistic@mamot.fr The worst DRM experience that I've had was with ITunes. I was an early adopter and had purchased tons of music with DRM. When Apple finally switched, I was told that it would cost me $500 to convert my library. Haven't purchased DRM'd since, and I've kept anything important to me in text files. It's not just that proprietary formats are wrong from a political perspective -- you're also very likely to outlive them.
