This is not your fight. ETH can and will be fine. If it had been a bug in the EVM, fork-away. It wasn't, and all you have done with your meddling is destroy any trust anyone had, in running a trust-less system.
If Vitalik wasn't also a Curator and thus implied promoter of the DAO, then I'd agree with you 100%[1]. Let Tual et al, take any legal liability. But I am thinking maybe Vitalik is legally in deep shit also:
https://bitcointalk.org/index.php?topic=1517223.0But maybe you are correct and the lawyers will advise the Ethereum Foundation to do nothing, so as to not admit they are the ones "securing" the investments of the users so they don't fall under purview of the securities law. But I still think they are going to damned because they didn't make adequate disclosures.
Nobody from their camp warned anything while the DAO was accumulating $168m. I and others were warning that this huge pot of egold ripe for losses (either exchange value losses or outright technological losses) and not making proper disclosure was going to end up a legal clusterfuck. So now here we are.
Bitcoin didn't have a key personality as a promoter.
[1] But that would mean I also agree the majority can do a 51% attack and change the protocol.
