Your story reminded me of a study in which students were more supportive of a safety measure that would save 85% of 150 lives than one that would save 150 lives. People commonly think in relative terms and may not be sure if 1 life or 150 lives is a lot. But 85% sounds like a lot. And 0.0001% surely doesn't. As you correctly point out, though, these proportions don't matter to the lives of the people being helped or saved.
Regarding why companies don't publicize following through on their commitments, this study suggests that most consumers don't care much about these commitments. So companies may not see much incentive in doing so.
