Does Bitcoin even give a shit about decentralization anymore? Seems mostly captured by custodians, and only thing that matters is number go up? 

In some of those cases, you can’t even go from custodial to non-custodial (ETFs).

Custodians are safer for the vast majority of people. Why would that mean they don’t value decentralization?

The whole genesis of BTC was that we couldn’t trust centralized actors to not screw us over. 

BTC as a community has worked politically to drive value up and get large centralized actors involved rather than the original P2P vision. Literally in the whitepaper

I don’t get why this is mutually exclusive with custodians? Everyone is free to self custody and likely increasingly will in the future. Your vision is clearly as strong as ever
