So, this gem uses the mime database provided by freedesktop.org when the gem could have got the database from http://www.iana.org/assignments/media-types/media-types.xhtml http://www.iana.org/assignments/media-types/media-types.xhtm... which wouldn't be GPL? What manipulation is done by freedesktop.org?

The gem is basically a database of mime type, file extension, and magic bytes. The last two are not included in the linked iana database.
