Doug McCune is reporting that there is a clause in the Widget Design Challenge 2008 contest being run by eBay that bars entrants from using open source libraries in their entries.
I'm referring to the blog post by David Arno that asks Has Adobe just killed SWX?
David's post refers to the recent opening of the AMF format (good one, Adobe, and about time, I'd say) and the open source release of BlazeDS.
