YC's way of operating is globally optimal. The cost (in money and time) of adequately vetting every company they've ever invested in would dwarf the cost of this little brouhaha. Even in later rounds due diligence skews non-technical. E.g. for Series A it mostly takes the form of "What licenses do your OSS dependencies use?", and (for B2B SaaS) "We want to talk to a half-dozen of your customers, preferably of different sizes and from different industries, and ideally one that's renewed".
