Not ridiculous at all. I usually buy after comparing specs & prices first, then look to what the Company/Leadership means to me.
MacApple means liberal $$ to me, so I go elsewhere.
Its not the employees, but the B.O.D. and the CEO I have interest in. Workerbees can be lib or conservative, makes no difference to me whatsoever.
Steve Jobs' politics don't suit me and I have equivalent or better products outside of Appleland Yes, Im a Geek & built-up my own computer. Man, I hate to admit that in public-don't tell anyone ;)
I know how much I would get for doing same on my Macs. About 10 cents in 12 years.
