Something like "Yes, this individual did not have a great education in youth because their local school district sucked. Nevertheless, this individual has potential. So we're committed to keeping this person on board and providing the necessary training. We will go to great lengths to make this person a useful and vital part of this company."
And you do it not just because you want to tick off some numbers, but you do it because a diverse workforce is going to create a more valuable and relevant company.
I was asking if perhaps OP's data analysis was flawed because (for example) Apple might be counting Genius Bar employees as "tech" for the purposes of the diversity report... ie maybe Apple has the same difficulty hiring diverse candidates as Google for similar positions, OP's friend's experience notwithstanding.
If they were serious, they could look beyond their institutionally-placed (and fairly arbitrary, let's say it) obstacles, like Apple did for his friend; but they won't, which means they are not serious.
