Try removing Google from your search engines. If you still want it you can re-add it from search results (click address bar, a new search icon with a + should appear at the bottom) or Mycroft.
Also consider removing/dismissing Google from the new tab page. If you have disabled the option showing your most visited sites, enable it temporarily to remove Google and untick the "sponsored" option in the new tab cog icon on the top right.

Pretty fucked-up laws. A lot of lawsuits going on right now against AI companies for similar issues. In this case, StackOverflow is entitled to be compensated for its partnership, and because the answers are all CC BY-SA 3.0, no one can complain. Now, that SA? Whatever.
