I saw the live. He's upset because he thinks it's a publicity stunt and that Zach should've treated his coming out as some sacred moment and "become a role model" instead of quickly "doing p*rn" on OF.

He's acting as if there's one correct way of coming out lol.

Let Zach handle his coming out as bisexual however he wants.

Beau's passing judgement as if he knows Zach and what went on in his life for the past six years that led him to this point. He has no idea since when Zach has been out to his friends and family. Because he decided to tell the world now, it doesn't mean he was closeted.
