As long as they're upfront about what they collect and how to not send them data, am fine with it. Obviously opt-in is much proffered to opt-out, but from the Firefox Voice site, it clearly states sharing data is opt-in. My guess would be there isn't much of a point selling voice data from an open dataset. Also, since the code is in the open, it would be relatively easy to spot if they were sending data to somewhere they do not or record when they shouldn't.
