What brand? There is no brand. Please stop using silly arguments. We do not sell Sigil we give it away. We do not even accept donations.

If you actually read those calibre mac icon threads you can see that I already brought up the fact there was no clear licence or ownership.

Clear licence means the clearly written licence to use the icon in our software. You can *not* just grab artwork willy-nilly off the internet and use it. That licence must also be compatible with our Sigil GPL software license. Typically the copyright owner and/or creator of the icon must create the license and make that licence known.

As for what calibre is doing or has done with icons is not our concern.

Sorry but not interested. You can always build Sigil on your own for MacOS and use it privately but I am not interested in change just for the sake of change.
