Our versions of what's centralized and what's decentralized obviously differ greatly. Having more arbiters join ECAF won't make it more 'decentralized' if you think that, you're missing the point. More than the worry of corruption is the notion of having this body rule over us with powers (that can be ignored) to freeze accounts and reappropriate funds - thus having control over the immutability of the EOS blockchain. It's an oxymoron.
