Silverlight is proprietary. And it's just the same type of evil, but maybe at a lower degree (it's still based on proprietary codecs and the main implementation is not free/open source).
Developers choose flash because it's much more popular and has mature tools and a significant pool of experienced professionals who can work with it. It's not only about the technical features of Silverlight compared to Flash (Silverlight doesn't really stand out), it's also about the ecosystem.
