that was my take too. As with any company, if they can stop sharing revenue with third parties it seems almost inevitable that they will. It isn't just Amazon basics, its Netflix producing its own shows that are a product of machine learning about people's preferences.

Whether that is good or bad is a different question

Whether they are being honest about it is a different question

Whether they should inform people / people should inform themselves is a different question

But I see the perverse incentives as a problem, and the the misleading behavior as another the problem...the incentive is universal in any platform that has to pay for the content it hosts, and while folks may be okay with this one, whats the limit? If they really stood behind this they would be transparent 'here I'm playing you music created by spotify to fill your home with generic low-engagement sound. The fact that they are obfuscating it is telling.
