Charles has agreed that PoS requires centralized checkpointing:

You will need some hard checkpoints. In my opinion, a widely disbursed and actively staked coin does not need a checkpoint server. So the centralization would come from the source code, just like the protocol rules do for every coin.

you either have checkpoints or you dont. having just some hardcoded checkpoints makes no sense? Huh

There is a big difference. In one case the checkpoints are controlled by a single node and are given out to the network on the fly, in the other case there are maybe 5-10 hardcoded checkpoints in the source code.

In the case of a checkpoint server, it is truly centralized control and choice of the chain. In the case of the hardcoded checkpoints, it is simply cementing in the blockchain, usually months or more, in the past. There is a huge difference, don't know how you could argue that there isn't. In one case you have trust in one specific node, in the other your trust is given to the source code that you built from.
