What other option is there? Same could be said about how knowing the internals of your car, or your house, your plumbing system, your electrical connection, hell even your health all matter because not knowing means the providers / maintainers / engineers can take advantage of you.

Caveat emptor doesn't go away with time. And I don't believe trying to use the hammer of legislation on the various hooks of businesses is an effective or even ethical way to try to "solve" it.
