Preedit writes to tell us that those busy folks over at InformationWeek have been scrutinizing yet more SEC filings, and Novell and Microsoft aren't the only ones concerned about certain provisions in the final draft of GPLv3. TiVo worries too. The problem is that TiVo boxes are Linux-based. They're also designed to shut down if the software is hacked by users trying to circumvent DRM features. But GPLv3 would prohibit TiVo's no-tamper setup. "If the currently proposed version of GPLv3 is widely adopted, we may be unable to incorporate future enhancements to the GNU/Linux operating system into our software, which could adversely affect our business," TiVo warns in a regulatory filing cited by InformationWeek."
