I read this as "military industrial complex" and was positively surprised to see such a strong sociopolitical statement coming from Tim Cook, then I noticed the article talks about "data industrial complex" and realised this is still tame enough to count as aggressive marketing.
Apple can effect data industrial complex, unlike the military industrial complex. Doing the opposite would be empty posturing.
Publicly attacking the military industrial complex would be opposed to Apple's economical interests (because it might upset a segment of its customers).
It's difficult to judge the sincerity of moral outrage in an attack that aligns with your own economical interests. You may think of it as "empty posturing" but speaking out against a sociopolitical issue you're not directly part of can help bring about changes and can help shape cultural attitudes.
For example, coming out as gay in 2014 wasn't necessarily in Tim Cook's best economical or even personal interest (though those offended or upset by this are less likely to let that affect doing business with him because after all he's still the CEO of one of the largest corporations) but it may have played a small part in changing overall social attitudes (remember that the Supreme Court decision on equal marriage in 2015 only happened after most states had already passed equivalent legislation and public support had been fairly widespread).
You may not be able to change something by calling out. But you certainly don't change it by remaining silent about it and playing along with the status quo.
