No I think it's predicated on creating a product that people like to use. That's the Step 1 that OSS zealots miss when they focus entirely on these niche lofty ideals. I highly doubt the average Instagram user is yearning for - or would even be enticed by - a version of that same experience that has a lower exit cost.

That's the problem with these Twitter clones. "It's just like Twitter, but RESPECTS your data ownership" is not compelling. Just create a freaking compelling and original user experience (the actual hard part that made the big platforms successful) and secretly do whatever you want on the back end.
