> Adobe has never gone after these open source swf player projects.
They went after rtmpdump, a tool developed by the gnash devs after clean-room reverse engineering to eventually bring RTMP support (client video streaming) to gnash and other free players:

> rtmpdump is an open-source command-line tool that is designed to dump the full RTMP stream. It implements the RTMPE protocol, which Adobe believes to be an encryption and copyright protection scheme: however analysis of RTMPE shows that RTMPE is nothing of the kind. rtmpdump was removed from its original SourceForge page due to Adobe issuing a Digital Millennium Copyright Act takedown notice, which Sourceforge did not have the resources to contest, and could not place any other sourceforge projects at risk. flvstreamer is a fork of rtmpdump which removes all the code that Adobe believed was in violation of the DMCA (due to the belief by Adobe that RTMPE is an encryption mechanism). flvstreamer still allows users to download a stream of audio or video content from all RTMP servers, as long as RTMPE is not enabled on the server. rtmpdump development was restarted in October 2009 and is hosted at the MPlayer site[5]. It has much improved functionality and has been rewritten in C (was C++).
