EFF points to DRM as a driver of vendor lock-in. I would point to opaque, often proprietary standards for dynamic, user-hostile data formats. Word processing documents come to mind. DOCX and DOC never have been fully cross-vendor compatible as far as I can tell. And the leading word processor doesn't transparently support a format that is. The situation is improper it's an anti-social moat for the dominant software vendor to construct.
