It would appear that a similar thing has happened with 7ZIP, although I
am unaware of any legal issues on that front. I don't really know much
about File Roller (I rarely use GUI tools for such tasks), however on
examination it appears to not have options for changing compression
options. This might be a good spot for improvement of File Roller. I may
look into it.
