Leaving seems like almost zero representation to me. Now, it doesn't mean zero freedom, yes, people have freedom to leave. I just don't see that as representation.
Honestly, I'm not sure how it would look. I imagine it might feel different. I imagine I might feel a little more hopeful, instead of so helpless. A little more calm, less filled with dread. I imagine I might feel a little more relaxed, believing I have some say in a safety valve to keep the platform going, in case some leader takes it in a direction that most of us don't want.
I don't know if I'd even want direct democracy, where we users vote on feature prioritization and other nitty-gritty details, I may like some type of representative democracy.
I don't know. It may not look different but maybe it would feel different. Does that make any sense?
If Facebook makes you feel "helpless" and "filled with dread", then probably the most empowering choice is to stop using Facebook.
