I don't think there can be a satisfactory proposition of "accountability". We have an Oligarchic system which again, systematically undermines the rights of use

I don't think there can be a satisfactory proposition of "accountability". We have an Oligarchic system which again, systematically undermines the rights of users. Software which is made primarily for short term profit, will undervalue privacy, because it does not sell. Things are centralized because with the current technology that's how they scale, and are easier to control, and convenient. And also because data about you is important, that's the real treasure. De-centralization is what will give power back to users. Ofcourse I don't want every user configuring their own synchronization solution instead of using Dropbox, and Drive. But running your own server , with modular services like these (sync, backup, email etc), should be like installing apps on your phone.
