That’s not true. A bunch of publicly traded us miners mine for foundry. Hut 8, I think marathon, etc. they’re enterprise-focused, but they don’t own all their hashrate. 

Ah, didn't know that. Is that coz they control all the hardware or because of something else, like a protocol they run? 

Foundry is the largest and they control all their hashrate. You and I cannot mine for Foundry.

Do these top 3 miners take possession of the morning equipment and warehouse them (like compass)?

I don't think so. The mining pool operator doesn't have control over the individual miners. If a pool has bad behavior miners can switch to another pool.

I would want to see the distribution of hashrate by decision-making entities, but I don't know how to get that data.

The top 3 mining pools now have 54.8% of the total hashrate
