I think it depends on who your "target market" is. Non-viral licenses make sense if you want companies to use it.
I've never released my work under MIT or BSD. I release about half of my work into the public domain, about a quarter of it under a GPL variant, and a quarter of it remains under a more conventional commercial license.
