B. Imprinted logos can easily be cleaned with a toothpick. I didn't suggest embossed logos because (1) they make the surface uneven (2) it's harder to clean than imprinted.
C. The Mesa Boogie logo has a design that compliments the overall look of the product while SD pickups have plain text that contrasts with the color of the pickup.
D. The issue comes up a lot more than once per year and is mentioned frequently on other forums, Craig's List, Ebay, etc...
E. You said yourself that "it could be smaller" which means that you're not 100% satisfied and that you believe it could use some improvement. Given that fact, then why oppose the suggestion to leave it off or modify it?
F. As many people have stated, they want to modify their guitars with a period-correct look or maintain a clean look.
G. It seems backwards to have to pay extra to NOT advertise.
H. A pickup would have to be considered "modified" or not in original condition if the logo is removed. Whether you agree or not, it probably does have some effect (no matter how marginal it might be) on the value it maintains.
Here's the deal. I love Seymour Duncan pickups as much as anyone. I think they're some of the best pickups in the world. However, I prefer my pickups to look clean and match with the theme of my guitar rather than contrast with it. I think most people in some way agree. The title does nothing to enhance the look.

NO LOGO - CLEAN, SIMPLE
LOGO - SOMETHING BESIDES THE NATURAL LOOK OF THE PICKUP STANDS OUT
I think if we're all 100% honest, the majority would agree in some way. I'm sure that this same poll outside of the SD forum would a very high majority for no logo or modified logo. Therefore, it seems common sense that there is enough customer sentiment to take it into consideration and improve the design. Good companies are always looking to find ways to improve customer satisfaction and product quality. I don't see why some people take offense when someone offers suggestions for improvement.
