So what? Linking (both static and dynamic) is the same as framing 
and mounting.

If the framing process does not create a derivative work, then 
mounting [...] does not create a derivative work. What is more, 
the ninth circuit erred in assuming that normal means of 
mounting and displaying art are easily reversible. A painting 
is placed in a wooden "stretcher" as part of the framing 
process; this leads to some punctures (commonly tacks or 
staples), may entail trimming the edges of the canvas, and may 
affect the surface of the painting as well. Works by Jackson 
Pollock are notoriously hard to mount without damage, given the 
thickness of their paint. As a prelude to framing, photographs, 
prints, and posters may be mounted on stiff boards using wax 
sheets, but sometimes glue or another more durable substance is 
employed to create the bond.

Yeah. I know quite well that RMS is amusingly insane.

He and his "pro bono"-me counsel can't even grasp the difference 
between "derivative works" and "compilations" (collective works 
including).
