So many people are now excited to have a solution for their platforms. One of the big advantages of free software is the ability of people that have machines I don't own can help make it truly portable.

Most Flash movies on the Net are older Flash formats, which is why that's the current focus for the near term.

Gnash has been developed only using freely available documentation and tools, so it can be a free implementation of a closed proprietary format.

Gnash is GPL2'd, and the Free Software Foundation has the copyright. So the standalone player can be used by anyone, but the Flash player code can only be used by other free software projects under the terms of the GPL.
