A few things worth corecting.

1. Power badge is not required at the protocol; it's a Warpcast feature that we offer as an API for other apps. They have freedom to use or not use.

2. People don't want to see uninteresting accounts. So we offer a) who you follow and who follows you b) power badge. Again, on Warpcast.

Exactly, it gives edge to  Warpcast but might not work for all communities. That’s fine!!

BUT This is true example of how decentralized Farcaster network is. We will see more and more clients to have their own ways to classify content and users to serve their targeted audiences!
