I'm not denying it's technically feasible. I do deny learned helplessness. I have limited energy in life. Using it on making a change I'm not passionate about is a recipe for severe burnout. If i get more involved and find there's sentiment towards a migration away from FB then I'd spend some energy on building and facilitating that. Barging in and making demands isn't an effective way to build community. You can introduce ideas and develop them over time to show that it comes from care for and dedication to the org.
So yeah it's unrealistic on the time scales I'm concerned with.
