This doesn’t seem that surprising, most of these companies are “failures” - seems to stand to reason that many of these founders would cast some blame on the VCs (perhaps for not continuing to support the business when it was clear that it was not working). Also not surprising is the that VCs overestimate their value. Lastly founders probably have a much more diverse (and perhaps incorrect view - probably fostered by the VCs) of actual value add of VCs.
