The same can be said when you give someone power, but then don't pay them enough. Even the most honest people can be corrupted when it means being able to feed or not feed your family.
One reason low prices of Steem are good right now that is hardly talked about is that it helps to distribute the power. Look at EOS that's being taken over by the Chinese.
I'm sure some of the information is FUD, but I'm sure there is also a little truth behind it as well. The better Steem is distributed the better DPOS runs and the more people who are "vested" in the long term success of Steem.
