one does what one must. it's wrong-headed for companies to not hire based on an offense that is immaterial to them.

So, disclose it when asked a relevant question, but get a name change anyway. It might be the media directly tied to you that companies are avoiding as much as your past: inevitably, your name will be attached to the company publicly (most likely) and they may not want that kind of 2-step search connection.

I get the ethical concern about hiding something that would be a deal breaker, so don't do that. But also don't create an unnecessary PR issue for a potential employer.
