As pointed out in the comments he didn't have 11M followers. @music was renamed to @musicfan and @twittermusic was renamed to @music. Both accounts kept all of their followers.
It's pretty awful to look at people who point out dishonesty on your side and see a supporter of the enemy. Without that premise, directing your question at somebody who pointed out an error/deception that you did not bother to dispute would be a non-sequitur.
Why do you think that somebody who points out dishonesty would think what happened is "completely ok"?
