One thing to consider in the moral judgement of behavior is the role of intention. If a person's behavior is intended toward a specific outcome that is benificent, then it should be considered less wrong than behavior that is intended toward a specific outcome that is malicious, regardless of the actual outcome. In the context of misinforming vs uninforming, if the intended outcome is the same for either behavior, then why should either behavior be deemed as less wrong than the other (especially when the actual outcome is the same)?

In the Walrus and Carpenter scenarios, both scenarios involve Walrus intentionally and successfully obscuring the truth with the same outcome. Whether or not Walrus's intentions are ultimately beneficent or malicious is undetermined. Regardless, I would not consider Walrus's behavior in either scenario less wrong than that of the other scenario.
