Solid Oak Software, the company behind the CyberSitter program, has sent cease and desist letters to Dell and Hewlett-Packard. The letters are in regards to the Green Dam software that the Chinese government will be requiring all PCs sold in China to have installed. Solid Oak claims that the Chinese company responsible for the filtering software stole a good deal of the code from CyberSitter. Solid Oak wishes to take legal action against the Chinese company, but certainly doesn't blame the PC manufacturers. China has been criticized for the mandatory filter, and there are a few organizations that wold like to talk them out of it.
