The extra income; the tremendous platform to promote her new album - something she didn't get with UEDS; the statement it would made to the French people that she STILL matters! Yes, I think it's worth it.
She's not really "leaving" her Mexican fans. I don't think The Voice would have been a year-round commitment anyways. Plus, I think her Mexican fans would have been more than happy if Alizee can travel there even once a year. (I would 'cause it'll be closer from San Diego
)
Of course, all of these are water under the bridge now.
