Maybe it's like in Germany, where Quake in all its variants is forbidden and evil. Hence if you want to advertise it in your catalogue (NO PICTARS), you write Q**** instead, or the german word for quake, 'beben'. Everyone knows what you're talking about, except the powers that be. Or maybe they do know, but you can always feign ignorance. And it's just like that. I expect that if I'd ever dare write Micro$oft the real way, the fiery pits of hell would open up beneath me and swallow me whole. I'd probably land butt-first in a pile of pitchforks. Oh the stinging.
