This may have used to be true to a degree, but the console makers don't really sell consoles at a loss anymore, or a minor loss at launch knowing that they will turn a profit soon enough on the hardware once they reach volume.

Not sure what the point is supposed to be with "The value of creating and enabling an entire ecosystem is found to be worth 30%", and making the judgment that Apple hasn't done the same. Without some harder numbers on both sides, it's not a conclusion that anyone is in the position to make. It's also worth remembering that Apple has amassed an extremely loyal customer base that has shown that they are willing to spend an immense amount of money on App Store purchases over the period of decades - Apple does deserve to cash in on that value created such as being the single point of contact for easily addressable issues with app purchases, fraud, & such for the customer, secure & frictionless payments, and most of all, creating the situation where users want to go and spend $ on their platform over alternatives.

The value created is in developers/publishers being able to make more $, which is the ultimate value.
