Because Makani was by far the best funded startup in this space and they got very far. Very easy to understand why I'd say. As to fly-gen, it has several benefits, like continuous power delivery and not least an easy way to launch and land - you already have the propellers. The main downsides are complexity, weight, and the weight and girth of the tether needed to transfer the power. The drag from the tether is significant. Plus the sound of the blades.
