That’s precisely why they don’t want you cheating the hard part and just storing the results. It makes sense to me. Work on your own machine learning if you want good results.
There is no such thing as cheating, only staying within boundaries that don't land you in jail or sued in your own jurisdiction. If you can get an edge by using Google's own data, do so.
You could argue that Google should work on their own knowledge database instead of learning from other people's content and/or presenting other people's content in their own frontends (shopping etc)...
