The issue is, given the power inherent to moderation, how is that power best managed? Do you want it applied by whoever happens to own the platform (previously “liberal” publicly owned Twitter, Elon owned Twitter, etc?), or do you want to have decentralized control over that power?

You talk about getting “viewpoints widened”, as though all speech has inherent value to all people. I’m not sure the evidence bears that out. Simply being exposed to other people’s viewpoints doesn’t necessarily lead to a mind opening experience, especially when that exposure is little more than shouting over text, piling on, and mudslinging. Discourse requires a base level of accepted rules of engagement and norms of behavior that lead to some level of mutual respect.

I’m personally optimistic that blue sky’s approach is closer to the ideal.
