Oh, please stop whining about Apple not including a higher spec USB-C cable.
Let's consider the below calculations for 10.000.000 Pro phones:
Cost of TB cable: 5$ --> cost for 10 mil. phones --> 50 mil. $
Out of the 10 mil. owners probably 10% will need a TB cable.
Out of those, probably 10% will buy a TB cable from Apple --> 1% of phone buyers.
So Apple can expect to sell 1% x 10 mil. --> 100.000 TB cables.
Apple sells a 2m TB cable for 40$, cost is 5$ so profit per cable is 35$.
They would make 35$ x 100.000 = 3.5 mil. $ profit from the cable sales.
Now, as a company, what would you choose: a 50 mil. $ cost or a 3.5 mil $ profit?
Apple will manufacture at least 30 mil. Pro phones, so multiply the above by 3.
You need to understand that Apple is a commercial company and it's primary scope is to make profit for it's shareholders.
