My hypothesis is that if you give people easy ways to do the right thing, they tend to value doing so[1]. It is one thing to know "vague horrible things happen elsewhere to give me my current standard of living" and a different one to provide actionable and timely choices to diminish that harm. So it's good that companies are improving their practices and making that a marketing point (even if "we are better that the competition... because we decided to recently stop funding warlords" is perhaps a fairly low standard). In the end, the right solutions may go beyond this, involving regulations and government incentives and treaties, and stronger governance developing in affected countries; but as far as what Intel can do and what individual consumers can do, it is still something.
[1] Failing that, one can advocate for taxing the wrong the choice (Banning the wrong choice might work too, if a reasonable substitute exists. May backfire otherwise, see: drugs).
