There's no > "circumvention". Yes, it is mostly clear, and indeed GPL3 seems a little bit over engineered, but that doesn't mean that GPL2 could not have any loopholes: 1. Release a kernel with builtin DRM for video. (For example HDCP [1]) Such DRM implementation is released under the GPL2 by copyright holder A. 2. Distribute a modified kernel without DRM. Copyright holder A gave you permission to do so, by the GPL2, everything is OK. 3. People can backup videos from copyright holder B using the modified kernel. 4. Copyright holder B can sue you under the DMCA, for circumventing an effective technological measure. It doesn't matter whatever license copyright holder A gave you. Regards, Emilio Footnotes: [1] High-Bandwidth Digital Content Protection. Currently you would never get a license for a GPL implementation, but it's used as an hypothetical example. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
