I watched his Vanity Fair video.
He did the song and dance about his abusive actions towards Cassie "not being who he is" even though it was him that did all of that. He also said that he acted out because he felt that Cassie was his, "last straight relationship." At the same time he said he really only came out and told his publicist after he received that email about him hooking up in a bathhouse (likely nude). When asked if he reached out to Cassie after telling the world that she was nothing more than a beard or person for him to own (via his stalking) he said "No" then smiled.
Now he wants nothing more than to be married and have children with his future husband. He's also listened and taken to heart the criticism he's received, but wouldn't be changing anything. If he could do it all over again he'd still be on the Bachelor, coming out on GMA, and do his Netflix show (i'm assuming that last bit).
Basically, he knew he was lying through his teeth during the Bachelor and when he wrote his book about being a straight. I feel like his only regret is that trip to the bathhouse and maybe the Grindr hookups. He's certainly let his hair down and dropped some of his (traditionally) straight facade which is nice. I hope he's enjoying his new found freedom. Beyond that, he didn't have much more to offer; he's rather bland on screen.
Expect a reenactment of the outing screen from "Love, Simmon" during an episode where he recaps his experience with that email. There will be tears, there will be hugs, and when the cameras stop, loads will be shared.
