btw: Having a ringtone contest now, where not even a prototype exists, is pretty pointless.
Ringtones are subject to fashion. It will be at least 1.5 years before the Librem 5 will be released. Nobody knows what will be fashionable at that time. If for some reason Purism feels the need to change the default ringtone by that time, then the current contest will have been pointless.
