Personally while I love the rubies... I wouldn't mind for an "hostile takeover" of the company from the women they sought to control in the first place.
I think this is the only logical move to the girls, if they control Monsonis, they control everything. Their only chance is to reprogram Monsonis's ruby to make him do what they want. If they just get the rubies off and make a run for it, how long can they seriously expect to remain free, even if they free all the women, once Monsonis is back in control, it just a matter of restoring the programming to the rubies and placing them back on the women. It wouldn't be terribly hard to sneak up behind a woman and quick place a ruby on there arm or neck, instant slave.
Even if they free themselves, it appears there increase sex drive is a permanent, Rubies or not. When Gabby and Elaine Rubies were offline, they still couldn't control themselves having wild sex together and with other men. It looks like they are slaves to there new desires, they will little control over there futures, regardless of the outcome.
Also I'm not sure the women's motives are all that pure, one asks Nick if she can keep one of the girls as her own slave. Maybe they are perfectly fine with women slaves, just so long as they are in control.
Nick doesn't appear to be that much of a "nice guy" like Gabby says. Nice guys don't cheat on there wife's, and enslave her and her friends. He's just upset he's no longer in charge of his Wife and Harem, I think if he had a chance to regain control over his Wife, he be more than happy to make them all his personal slaves again.
