"Knowing," "intended [at the time]", "would end up being shut down by regulators" are all your embellishments. The claim is "YC funded a payday lender that targeted active duty military service members." As far as I can tell, that is true, regardless of how pure anyone's intentions were at the time. The defense on offer is that the founders left the company between funding and now, but it is not very compelling given the timelines.
