What are you on about? The open letter was specifically advocating against sponsorships and advertisements of the Military Industrial Complex. I.E. private companies who specifically try to turn a profit from countries going to war. Companies that literally earn money over people’s dead bodies. I think the people that wrote the open letter were very aware that being sponsored by the military was something that is hard to avoid. However there is a clear difference between being sponsored by a military and being sponsored by, like, literal death merchants
