I think you still have to qualify that as 'moral or ethical credibility', and even then limit it to topics relating to government power and accountability.

By all accounts, their treatment of founders is very ethical indeed (by Founders' standards), for example, and I wouldn't expect this to impact their credibility as knowledgable VCs at all.

In short, people are complicated, and applying well-earned admiration in one area to transitively enhance someone's reputation in another is clearly an all too common error (hence celebrity endorsements, etc.)
