* Given that for-profits can be given tax-breaks for (hopefully) good reasons [which are not altruistic];

A defense contractor designing missile guidance qualifies for the Exempt Purpose of "scientific."

A megachurch with a private jet qualifies under its "religious" category.

These do not specifically require altruistic intent. Congress chose to subsidize certain categories of activity (religious, scientific, educational, and so on) because it wanted more of that activity produced, regardless of the motives of the people doing it.
