I'm not going to blame Fitbit. But they didn't earn any positive karma, either.
Nor am I surprised that the real reason came out of the blue, after it was too late to inform my decision (I would have bought one for spare, while supplies lasted).
Emphasis with Kickstarter is "start". Then it quickly morphs (usually) into the same old close-to-the-vest business wisdom, and you end up with half of the advantage you wished for, and a quarter as much stability as a going concern.
I have zero interest in any other smart watch.
Sigh. It's a sad thing.
