First, Ask should be big and smart enough to know that arbitrage is a money loser.
Second, checking a few of their pages, I don't consider that arbitrage. It's not as if the ads are right there in your face. Also, most of their pages there would be little to no ads for it. The "how much water should I drink" page has 3 ads, none of which is related. Same for a few other pages I just checked.
Must be a slow news day at SEL for them to comment/complain about this.
I can tell you however that Ask does bid on generic terms to get people to their site judging by the Adwords auction insights report. They also use generic ads. I don't see how this can be profitable for them. Maybe they have the money and just don't care for now, simply wanting people to use their site.
