There is one very good reason to reference your logo. If it ever changes, you
want to change it once and have that change appear everywhere. This happened to
me two years ago. Marketing will probably not change their minds based on an
objection from the tech writers!
It also happens in a single-sourcing scenario if you have to rebrand a doc set
for a partner with a different logo.
And another time this comes up is if you have a different logo for online use
(color) than for print use (b/w). When I generate my outputs, I use the color
logo for online help and online docs (PDF), and the b/w version for the printed
docs. Our logo is red, so a crisp black logo looks much better than a grayscale
version of the red one.
