Slock.it was very irresponsible not to cap The DAO from the beginning. Growing pains.
I didn't vote with carbonvote.com because I didn't have to. It was clear the HF was going to win. No need to mess with my cold wallets. There was no perfect outcome from this situation, but I see the HF as the least bad.
IMHO Bitcoin could use a HF, but they can't get one due to the centralization of mining in a few Chinese companies. I see that as a negative.
The threshold for a HF will likely grow for Ethereum as the network grows due to the diversity of stakeholders and their interests. These are very early times for Ethereum, and even for Bitcoin.
Ethereum does have more scheduled hard forks coming, BTW. The switch to PoS is going to require one.
