That ignores the fact that some of those people, usually the ones in power, are either heartless bastards or, more often, sufficiently involved in making the company succeed to forego altruism. Making sure your employees keep their jobs often counts for more than being kind to strangers.
However, there is another way in which capitalism makes things better: it does its best to find markets for everything. For instance, Unilever sells very small packages of washing powder in India, which is optimized to be used in rivers. Previously, people in India did not have access to washing powder (the regular large packages were too expensive and the stuff wasn't very useful in the river). Now they have access to washing powder, which improves hygiene.
However, instructions on packages of washing powder are not printed in braille.

What an awful example.
Before washing powder, people used a bar of wash soap: cheaper, more convenient, purpose-designed and doesn't come in single-use packages encouraging you to use more than you need. (Wash soap also does a much better job than any powder I have tried when hand-washing, although YMMV.)
This sounds like a classic case of a large corporation's marketing department convincing people to buy a product that is more expensive and no better (and possibly worse) than what they currently have.
I don't think an explanation involving 'YMMV' and 'sounds like' is a sufficient support for your opening statement that it is 'an awful example'.
They have simply entered a market with a competing product. Unless you have evidence that their product is inferior to competing solutions and that they know it, but intend to overcome that problem by outmarketing the competition, then you really don't have any support for your position. Nestle has nothing to do with it until then.
I'm only relaying what I've heard an employee tell and I assume good faith: they changed their product such that it would be suitable for a new market and a nice side effect is that the product becomes available at all (which is nice because it improves matters). I have no stake in this and will readily revise my ideas, but not based on an unsupported accusation.
