Is this not against Google's terms of service? Could they not make legal threats? And ban the company from using all Google products like Gmail and ads? I know there's companies doing similar things and I'm not saying they should get in trouble, but it feels so risky basing a business around it, unless I'm missing something. Lots of companies seem to do similar scraping to get SEO data for example that Google probably has an interest in preventing.
