This is a good verdict - defamation in the media is a very serious problem. It's unfortunate that it took a person like Alex Jones to convince people of it. If anything he should not be taken seriously. Those who are taken seriously have gotten away with much worse by merely apologizing or correcting themselves (as he did as well).
As for the amount - the highest fine paid by Wall Street firms for the 2008 crisis was less than $100M. One of those numbers is unjust for sure.
