That is cool. Maybe I’ll buy that issue “for my boyfriend”! As for motivations, my guess would lean towards one of two scenarios. A: the graphic designer was being subversive and wanted to spread the good word, or B: the graphic designer wishes he worked in Redmond and hates the damn copyleft commies. Probably, in either case, the caption has nothing to do with the fact that the t-shirt has a creative commies logo on it. I really don’t buy the creative commies t-shirts = subrurban consumption theory and if that was their intent they would have explained the symbol since outside the open-source leaning blogosphere that icon is very little kown.
