DPOS witness tribalism is strong, very strong. Centralization is an interesting way to classify it.

My issue with it is in how many systems can a (top) witness be effective and work for the system and community at the same time.

I will seriously reconsider my Top 20 witness votes once the other platforms launch and I notice witnesses campaigning even harder in the new(er) communities, which means they dedicate less time us.

At that point I will also consider whether they DP or even short Steem.
