My perspective: the incentive for manufacturers is to generate as much revenue as possible. In hardware manufacturing, margins are extremely tight.
Consequently, any additional revenue from selling customer data is incredibly attractive.
Especially if you can do so better/faster than your competitors, thereby competing at the same retail price points with better net margins.
As a result... they have every incentive to fuck their customers over from a privacy perspective.
And what they're doing is invisible.
And this is an entity people are comfortable trusting with unfettered access to their devices/network?
