Sorry, but it seems like a silly idea. If the petition was to "Release the source code as open source for DPaint" then i'd sign it and be "all for it". But to try and get THEM to port an old application with no market is insane.
That's exactly what I was thinking. EA is beyond applications and they know that there is no money to be made in consumer desktop applications.
Asking them to open source it now that would be smart. That way someone could make both a blue and red versions. ;-)
