That’s just a line. More like, “We can collect our own data”, or “We can lock them in and collect subscription fees.”
They already collect and track you, even with car play. I strongly recommend this CCC talk, where they hacked a Volkswagen database that contained unfiltered, high-accuracy, timestamped locations of a large majority of electric cars from VW group.
Based on that they were, for example, able to identify cars owned by members of Germany's security apparatus: where they work, where they live, where they drop off their children each morning. Who visited brothels.
