I should know better than to feed the troll but... I see no evidence they did anything but what was needed to bring the tablet forward. They wanted to invest in that direction, and the backing of the campaign was a way to taste the waters, and see there was demand for it. So they invested in it, adapting the software as needed to make it work on the tablet. And part of the work was useful in general, and we got it back as SailfishOS 2.0 on the phone. So how were they doing "completely different things"? The stretch goals were all software features, and too thinly veiled, and they got plenty of criticism during the campaign, but that only means they misjudged who their backers were, and how they could easily see through marketing speech. But I cannot see anything more malicious than that.
