The point that is being made is whether or not Sasuke fans will acknowledge that Sasuke is using the same means to try to beat Naruto that you looked down on Naruto all of these years for using. They won't, so don't hold your breath. Obviously Sasuke doesn't think he can win any other way. Now that Naruto has gotten serious he will have a rude awakening.
Another point is how hypocritical Sasuke is being. A few chapters ago he looked down on Madara after the sage said he was dying and Sasuke stated that Madara deserved it for having used the tailed beasts. Shouldn't that also apply to him? Obviously he doesn't believe so since he holds the power now.
Sasuke has shown that he has sunk as low as Obito and Madara by using the tailed beasts. He's doing the same thing that he looked down on Madara for doing. Naruto will not kill him but he will come to realize he cannot beat him either. Naruto might end up almost killing him and then bringing him back like he did for Guy and Obito.
He already realized that he needs the tailed beast power against Naruto so he has fallen into the same trap as Obito and Madara, this won't end well for him. It shows that he will do anything to win and Naruto can't let that slide because it means he would do anything as a ruler too. The power has already corrupted him.
