I'm suprised this isn't a greater issue with advertisers.
I know most advertisers haven't experienced google's comparison ads because they are not affected by this particular vertical. However, if they are doing this now in mortgage, I'm sure its not going to be long before they expand to other industries.
Take a look and type in the term "mortgage". Imagine when they do similar stuff with shopping engines, medical services, attorneys, lead generation, etc. Very scary.
