There is always a point to demonstrate demand, so vote if you care. They easily can have the capabilities (they can just use the proper modem in the next batch). I don't think hardware is an issue for them, but legal threats are.

Not sure whether it was right or wrong, but it's not based on any demand, but rather on risks. I'd expect the level of demand in US to be not lower than in Europe. The device now is used mostly by enthusiasts anyway and general public has no clue about Jolla, whether in Europe or elsewhere, and Jolla are OK with that, while it fits their production capacity. When Jolla will decide to change that, they'll pour more resources in marketing.
