No, you also can't charge for mods. And no, the EULA hasn't changed. These have been the rules since forever.
And, no, this is not "the end of Minecraft".
Servers selling ("rewards for donations" is selling) items are turning the game into a F2P game. I absolutely HATE F2P, with a passion.
Well, I guess hate is a bit of a strong word. I dislike it about as much as I dislike popcorn stuck between teeth.
