I agree with your point of view but there is nothing that can be done about it.
It does feel sad to see one giant instance have almost all users and all traffic for me too. I was hoping it would become a proper decentralized platform with hundreds of islands of different servers filled with people and communities.
But fine, we don’t always get what we want. I’m disappointed but will keep using Lemmy anyway. It’s not a big tech service at least which is wonderful, and most people are nice.
