Weak links in the chain
On the one hand, it can be tempting to think that the user who allows their password backdoor to be something as simple as identifying that their favorite food is pizza deserves what they get.

On the other hand, cumulatively speaking, each vulnerable user collectively makes everyone else vulnerable because it then makes the encrypted data -- should that ever become compromised -- easier to decrypt.

(Case in point: Adobe)

The Fault is in the Questioner not the Questioned
I agree that this represents a major security flaw. But the issue resides with the provider of the security questions. The questions cannot be generic, "What's your favorite food or color" because there is only a very small amount of choices that could be selected.

Something to the effect of what hospital were you born at, etc is more difficult to predict but can be discerned through research. All in all, these types of security mechanisms are weak. "What we know" is weaker than "What we have", so why not transition entirely to separate device authentication? The security question is a prelavent mechanism that seems antiquated.
