alt Hacker News> enter a co-op model where you're still effectively renting access to hardware that you don't directly own
If we're imagining a co-op, then the participants should all be equal owners in an organisation that owns the hardware itself, otherwise it's not much of a co-op really.
But at that point you don't have the same sort of security guarantees about the hardware. This isn't like a farming co-op where a single expensive piece of equipment gets passed around to each participant one week at a time. There needs to be either an economic, security, or other advantage to entering into this arrangement for a medium to large sized player that would otherwise be colocating multiple racks in a privately owned datacenter or else renting bare metal instances in bulk from one of the hyperscalers.
