Not defending him, but it looks like he's not even looking, so he could have thought it was the guy pulling on the choke at first, but after Marc goes to 2 hands, there's no excuse, and the second you respond with attacking the ref, you should be out of the sport. Period.
Goddard tends to intervene more, and strongly. Granted, I've more often agreed with his interventions than not, but there are people who wants refs to basically influence nothing so the fight is purely affected by the fighters. But when you let that go too much, you get Herb Dean watching Conor basically further his criminal record while in the cage against Khabib, then making a dumb explanation video after. So when Goddard gets a situation like that and shuts that shit down, you get people going "Oh, here comes Goddard for the spotlight again!"
