It might be worth a calm call to them to say hey, I know you can't tell me why you revoked the offer, but contemporaneously with talking to you, my existing employer actually fired me saying that he could no longer trust me because I had looked for a new job, so obviously that's a little crazypants and not standard HR practice, and it made me wonder if he might also have lied when he spoke to you guys, since evidently he's both angry and vindictive. So in case it's something he said that triggered the revocation, I just wanted to give you that context and let you know there's a high chance he painted a false picture in order to torpedo the offer - he had been perfectly happy with me previously as evidenced by me working there 3 years, so there's really nothing true he could have said that would have been so negative.
I don't know employment law at all and this is not a law-based strategy, but people in recruiting departments are human and you might get lucky and have them reconsider. Maybe one of them has been lied about by a boss before - it happens.
I think this is worth a shot.
