Due to the TECHNICAL FACTS of how LZW works you cannot modify a LZW GIF without decompressing it first. Just as you must decompress a gzipped file before you may modify it. Are you going to tell me that some BSD compress'd program is GPL'd that it's not free because it is distributed as a .tar.Z? That's rediculous, but the same issue (and same algorithm in fact!) Nothing at all prevents you from modifying the source since there are free tools that can decompress the file (gzip can) and nothing is going to stop you from distributing an uncompressed (.tar) version of the source code or using a different compression scheme (.tar.gz) or a different packaging format for that matter (such as .zip) if you so choose. There is a problem in some cases (and there is a political statement to make in trying to put an end to the GIF format) but the problem just about never scales to the level that there are legal problems with GPL'd software just because they use GIF files. Even the FSF website admits that they could have used uncompressed GIFs, but has instead made the conscious choice to use something else and advocates that others do the same to help raise awareness of the issues regarding the LZW patent. Their choice was political, and so is your crusade. Don't think others so foolish to believe there is a serious legal issue here that is going to cause 50 packages to be pulled from the distribution if the problem isn't fixed before potato ships. > > There is no legal problem here.
