If I were to overly simplify, the summary of the OP Post is: "We reserve the right to lie, because we feel you can't handle the truth"
And many entrepreneurs respond: "If you can't feel fit to tell me the truth, then we don't have a relationship based on trust. And that means, there is no relationship."
If the OP's opinion is honest and forthright (ironic given that it is asserting a right to lie), then the entrepreneur's response is just as justified in being honest and forthright (we reserve the right to not work with liars).
If the desire to lie on the part of the VC is simply to avoid the pain of dealing with upset enterpreneurs or the potential of burning bridges, then they need to accept that they may offend other entrepreneurs who more value honesty over lying for the sake of avoiding hurt feelings.
