Why is Dietmar Hopp so hated?

I don't understand why Dietmar Hopp is so hated. I've read that because he'd bought a club which always played in lower level football leages, earlier, and he made it a rich club, that is why it reached the Bundesliga. And then? What wrong is in that? Why it is better if someone buy a well-known club which has a great past. What is the difference? He would been regarded as a better man if he too did so? There is a lot of billionairs in the world who buy football clubs in noted leagues. And many of them are obviously mafia chiefs. They are still not attacked in a considerable way.
