Fixing the DAO hack wasn't done via a 51% attack. In most/all blockchains protocol changes aren't done by simple majority vote.

Yes it was done by 51% attack. The chain split into ETH and ETC.
Not every chain split is a 51% attack.
Sure, some chain splits fail to get any significant support, so they don't reach anywhere near 51% of mining power. This one did. Hence, it's called a "51% attack".
