Any interventions imposed on Ocean would be enforced before any block is found. Like any centralized pool, condition can be put on the operators before anyone is even allowed to join the pool, let alone mine a block.

> Ocean has can reject the template or shares you submit to their pool server. The state can easily target Ocean and mandate conditions on what temaplates/shares they accept.

Yes they could.
But they cannot stop a miner from broadcasting a valid block.

That doesn't make Ocean decentralized. Ocean has can reject the template or shares you submit to their pool server. The state can easily target Ocean and mandate conditions on what temaplates/shares they accept. This is what we call a central point of failure.
