I'm assuming Tobi doesn't do it either because he's not a true Sharingan user (like Kakashi, swapped in an eye), which wouldn't be too much of a reach since he's already lied about quite a bit, or because the time Sasuke did it was with Kurama restrained. Essentially what Sasuke appeared to do was dispel the power Kurama was leaking out, which in the present case where Kurama himself is being released from the cage at Naruto's will, perhaps it's impossible to do because of some mechanic in the connection with the Jinchuuriki. Which would also slot in with how they had to forcibly capture the others instead of Tobi just going out himself and taming all of them.
