There are multiple antitrust cases facing Google, and this is just one of them. And these cases are clearly a very high priority for Google, all the way to the top. Google CEO Sundar Pichai has actually been sanctioned by at least one court for destroying documents related to his own conversations about these cases. Apparently chat logs show the SF "that Pichai personally asked whether a chat group's history could be turned off and then attempted to delete that message." The Antitrust Division says that Google has destroyed documents in its case as well. This kind of behavior isn't just an indication of bad faith, but of deep concern. Google's CEO is clearly thinking hard about the legal environment, because Pichai knows that how AI develops is as much a legal question as a scientific one.
