Some OS/2 fans are circulating a petition asking IBM to open the OS/2 source code. You can sign it here. Though IBM has become a good neighbor in the open source community, there are sometime tricky issues involved in open sourcing commercial software. For instance, IBM’s one-time collaborator in OS/2, Microsoft, may still own some of the OS/2 technology, and may not want to see it open sourced. Nevertheless, make your voice heard. It can’t hurt.
