"Bailout" generally means you paid off some group of people by taking money from taxpayers. In this case, the only person who lost money was the thief. I'd call it a recovery of stolen funds.

I was not invested in TheDAO but supported the fork mainly because (1) to anyone who's not a blockchain purist, if you can recover a stolen $50M you obviously should, and (2) it was early days, and the precautions the contract authors should have taken were undocumented and basically unknown to the community, so I thought more leeway was justified. Even the official documentation had similar flaws.
