They already confirmed the real madara was revived, Tobi is just some evil ally. The reason is they needed obito alive for kakashi and obito's character development. I chocked this one up to the fact that Naruto underestimated Obito's durability and im pretty sure he was unaware of Obito's enhance healing. Considering how bad that mask shattered. Any normal person would have died, the Rasengan was still spinning in his face after his mask shattered.

I highly doubt Naruto would have shed a tear if he never found out who was under the mask.

Also plot but given what we have seen from Obito and his mask until that point it isnt unreasonable that he survived the hit.
