I think it's because of the common assumption that the system that controls your data must also house the application that interacts with this data. When decentralized applications finally arrive (the inklings are already here) users won't be forced into this false choice. In that sense, companies like Google and Facebook are behind the curve, and don't really represent technological "advancement", but rather a social shift that has legitimized itself by falsely presenting itself as inevitable.

You just touched upon one of my idealistic geek wet dreams: Truly decentralized applications. Let's use ondemand music streaming as an example. I dream of a network where I pay whatever vendor I want, to deliver streams of music. I also pay whatever vendor I want to save my data (think playlists and play data). And I pay whatever vendor I want (could be free software as well) to play those streams. Each component does one thing, and the communication between is documented and open sourced. If I decide to switch player, that is fine, perhaps I use a different player on my phone and on my rpi terminal. If decide to switch stream provider my data is not locked with the previous vendor.

That's some idyllic thinking, but I agree such interoperability would be awesome. However, I don't see how it could be realized with current closed ecosystems. Seems like this would almost require open software...
