It's not as FUD-y as other's I've seen.<p><a href="https://bitcoinfoundation.org/2014/06/13/centralized-mining/" rel="nofollow">https://bitcoinfoundation.org/2014/06/13/centralized-mining/</a> is another good read. Where OP's link is more technical, this BCF link factors in the other side of things -- what would happen if someone actually did take advantage of this vulnerability.
