Well, 90% of her fan base was due to her formerly massive boobs. With a flat chest, she looks like an aging tranny street fighter. She looked extremely silly doing her micro jump/twist deal to shake her chest in the cage when she basically had no chest. I'm guessing she saw the money from horny Sherdoggers drying up so she figured she would be more secure going for win and eventual champion money.
Plus, she looked like shit in the fight. Got dominated for a portion of the 3rd with decent gnp. She loses the same fight if it was 5 rounds. Cyborg beats her like it's going out of style.
