msg.c is "partial" due to "michael", whose work can be changed to LGPL only once the core is LGPL. It's explained in the Copyright file. I prefer to do the relicensing incrementally (due to the overwhelming workload). Changing the license before that happens would be legally questionable, but nothing can stop us from essentially marking it as "will be LGPL". All authors have agreed to LGPL, with the following exceptions:9df11ee8bf: the author (probably) didn't agree, but the line that is added is later fully removed.35e90f1556: was not asked, but all iconv code was 100% removed from the mp_msg mechanism (we alwas require UTF-8 now).4e4f3f806e: the change by michael.50a86fcc34: the identify variable was move, and completely removed the latest in commit48bd03dd91.1f6c494641: did not agree, but due to a major mp_msg change the added line became unnecessary and was removed.da63498bf9: was not reachable, but the MPlayer GUI is gone from mpv anyway (also commitfc4d6e617dremoved these specific additions a long time ago).
