If what TPTB gave reason and Lien herself supports it, why still question it. Even if it's not, it's nearly a decade later. Nothing said or done can change it, so what's continuing to question it going to do? Voyager isn't going back into production and Lien isn't getting her job back. So even IF we find out what they said was a lie, what is it really going to change? If Kes fans REALLY are that upset, then they will still will be upset. Why carry around anger over something you still can't prove and can never change? What good is it ever going to do?
Who cares about doing good? This is the internet.
