It's very silly to say they "love" them. It's unlikely anyone is happy this happened. They are a news company, they report news, and people are interested most of all in bad things that have happened.
No it's not silly. These companies would be at a tiny fraction of their current revenue if people didn't like reading bad news and especially terrible tragedies. How much do you think their page views spike when there is an active manhunt or major events that happen? From a business perspective: they love them.
These media companies love tragedies like this. It is what makes them the most money. Why would they disable ads on their most lucrative pages?
