Given the permissiveness of the ICC license I find that statemnt not 
adequate. The ICC license allowes to modify the ICC profiles.

But with almost all modifications to a ICC profile the profile ID changes 
inherently. In that respect is is not like a program. So the ICC profile 
is not longer the original profile and thus the requirement has to be meet 
to avoid confusion. The whole issue is more compareable to cryptography. 
No one is going to "fix" a public SSH key and claim that is still that 
public key, which belonging to the original person. Such a behaviour is 
labeld fraud or naivity.

We have to ensure that ICC profile can be used and distributed together 
with GPLed software like SSH keys.
