"Do nothing until we've solved poverty." And there are many assumptions in your post that are not necessarily true: 1. Services could still be free to most users, with paid versions that provide more functionality. 2. Privacy invasion and advertising has a cost, that those very people worrying about food have to pay. They don't have to pay 2$/month for e-mail, but then will spend N$ for the expertly marketed toy/cereal their child is throwing a tantrum over, and their own purchasing choices will also be affected adversely - advertising works.
