The Ethereum Foundation owns and controls the trademarks of Ethereum. While they cannot dictate the code the various participants on the network run, they get to explicitly decide which version of the code gets to be called "Ethereum". That's how they maintain control.

There's a good chance that the trademark is no longer enforceable due to their failure to apply enforce it against Ethereum Classic. There has been quite a bit of discussion about this within the community.

Who should they have sued to enforce their trademark in the case of Ethereum Classic? Unless the argument is for genericization as opposed to failure to enforce, I don't understand.

The also own a lot of eth, directly and through their members private holdings. Keep in mind that Ethererum is mostly pre-mined.
