Concern about a Sun license

[Pierre Gruet <pgt@debian.org>]

Hello,

When working on igv (which is currently in non-free), I stumbled upon 
the license [0] including the following:

Sun grants you ("Licensee") a non-exclusive, royalty free, license to 
use, and redistribute this software graphics artwork, as individual 
graphics or as a collection, as part of software code or programs that 
you develop, provided that i) this copyright notice and license 
accompany the software graphics artwork; and ii) you do not utilize the 
software graphics artwork in a manner which is disparaging to Sun. 
Unless enforcement is prohibited by applicable law, you may not modify 
the graphics, and must use them true to color and unmodified in every way.

I feel that the "disparaging to Sun" part is a blocker for including the 
software in the main section. Do you agree?
And what about the last sentence?

I am a bit concerned because a check in sources.debian.org shows some 
software currently in main embed files with the "disparaging to Sun" part.

Thanks for your attention,

Best regards,
