I am a little confused now, sorry... ^^'

As far as I know, there is no company called Nostr. I tried to do a google search for companies with an ostrich as a logo, and there seem to be a few, but none in the Social Media space - meaning, it'd be totally fine to make hats with a white ostrich on a purple background. No company would be hurt by this ... as far as I am aware, anyway. o.o
