My users and I lose by buying Apple products.
I weep that Apple has entrenched themselves into the tech ecosystem. They take advantage of the least educated users fear and outright lie about security and product quality.
Is there anything we can do?
If you actually want to convince people, it might help not to start from the assumption of them being stupid.
Walk around at a physics conference, Google office, Harvard or MIT campus, and you'll see more MacBooks than any other brand. The notion of these users universally being clueless defies logic.
I'm not sure how that is relevant.
