Because I am constructing my own block templates and deciding what gets included in my blocks sovereignly from my node and mempool. The physical hardware matters less than the fact that the hardware is purely doing my software bidding.

I think you're conflating transaction selection with actual mining decentralization. The thing that datum does is transaction selection, at least in your case with renting hashrate. But it is *not* mining decentralization.

Renting hash rate from a centralized source undermines decentralization, much like the Fed's central control over money supply.
