Is this game really dead?

In my opionion, this game is really death now. The Updates, etc keeps going on, of course.

But if you see the player numbers then and compare it with now, you can actually see, that so much people left / quit this game.
I play only on an private server actually with friends, because this pvp community in Minecraft is really ... "bad" and full of kids (Since this game is prob. made for them).
