I don't think your question comes from the right corner of the problem space to begin with.

If you have a class of products which are linked with health problems in a subset of the population, and another set of problems that mitigate or eliminate said health problems in that subset of the population, then why should we complain about the products that are designed explicitly to protect your health?

And think about it: it your keyboard is causing health problems, why are you exploring solutions that involve perpetuating the root cause of your problem?
