I think it could be about hiding the level of accuracy. I remember sometime back learning that there are many cases where sounds are added back for comfort and the expected experience that customers are used to, so perhaps this is one of those cases where they have continued as a company to mask their true power and just like with everything they do, they cannot appear to be a monopoly so they need to fake the accuracy defects and all that while behind the scene they are actually tracking it all ..... who knows.
