I think Google would be happy to maintain such a product. Their problem is that they have no idea how to build it. They haven't created a single highly-profitable product since the launch of AdWords more than 20 years ago.
They've spent hundreds of billions on thousands of products, and they couldn't build a single one that actually took off. Think about that. It's truly incredible how incompetent they are as a company.
(Obviously YouTube and some other products are successful, but YouTube was an acquisition and nothing is wildly profitable like ads are.)
