There is one area with Permissioned Data Spaces that I haven't seen discussed. It reveals that data is currently stored in the (I think I'm coining a term here) *Public Space* on Personal Data Servers. Remember, most people on Bluesky aren't aware of where their data is stored, or what that means.

Aye > Data Ownership as a conversation changes when data resides primarily with people (..). > Instead of arguing for what kinds of data we ought to be able to download from the corporate silos, the platforms should be asking us what kinds of data they may copy from *our* servers.
