Also, another point: We had no indication that Salem knew what to do to activate the lamp. The last scene confirms that she doesn't know that she needs Jinn's name to summon her.

Well, Salem is shown to be willing to help all her followers archive their own goals (Watts - Revenge on Ironwood, Cinder - her lust for power, Hazel - Revenge from Ozpin, Tyrian - who knows). And Ruby was the one who decided to keep Ironwood in the dark. I wouldn't say she is at fault but I think the doubts make sense, especially from Yang who was the one most hurt by Ozpin's secrets because he broke a promise he made to her.
