I question what is going wrong with Google at a management level. It's products have been undergoing a slow creeping rot since Brin and Page bailed from the company.

Google Search as a product is declining in usefulness due to a very silly decision to no longer support lexical queries(!) They've built a broken AI fad that delivers nothing but song lyrics and shopping results to long tail queries. The core product is rotting and no one is empowered to fix it.
