I assume it's the Ziroth video that's linked, I watched it yesterday. This is a little different than Theranos in that there's multiple companies involved, but yeah, fake it till you make it gone wrong once again. It sounds like at least at some point, Donut Labs genuinely believed that CT Coatings actually had a revolutionary battery tech, and would eventually be able to supply it to them, per leaked emails between the companies, and maybe the initial fakery by Donut was just trying to bridge the gap until CT Coatings delivered what they promised. However, it's also clear that as time went on, the aggressive fundraising by Donut from small investors for a product that they continued to have no proof even existed, and the continued false claims about what they actually had, became hugely problematic. Exactly who knew what when within Donut Labs and the other involved companies, and what legal thresholds may have been crossed, remains to be seen.
