The problem is people. To put it charitably, not everyone is "technical" enough to figure out how to own their own data, so I think silos and walled gardens are here to stay, because they are quick and easy for people. I for one, fully support keeping my own data in (as much as possible) future-proof formats, and although I've had a blog in some form for years, I want to move away from standard social media as much as possible.
