Google Search Redirects to a Competitor

Here’s something I never thought I would see. When I did the Google search shown below, the Google Ad that was shown at the bottom of the search results was a link for a similar search by the Ask Search Site. According to this site, Ask has about 3% market share and Google is around 66% so it’s not like Google is directing users to a top competitor. Even so, I find it very strange that they are redirecting to Ask.
