I believe miners wouldn't, because while they might technically coordinate their efforts in deciding which version of a cryptocurrency to mine, they aren't pooling their resources and representing themselves as a single entity.

That's partly what makes these individuals an unincorporated organization.

They don't cooperate for profit, they compete with eachother.

Everyone in a mining (or staking) pool seems more likely to count as a general partnership.

ETH no longer has miners since the switch to PoS. There are now stakers, validators, liquid staking tokens, block builders, ... it has gotten a lot more complex than it was before.

What? Why would they be liable? The whole point is the liability in a partnership is shared between the partners: that is the entities that own the partnership.

Miners (staker?) aren't partners in the DAO: being a miner doesn't make you an owner of anything, anymore than being an employee or contractor to a partnership in the real world would make you liable for the actions of your employer/client.
