No and yes,

during creation it is completely considerd good practise to modify a ICC 
profile until its final. E.g. use Argyll to create a ICC profile and then 
add the meta tag with a more close to hardware+driver tool. That way PPD 
colour key words can walk into the profile. But that happens
before publicising.

Yes, I agree its a bad idea to modify ICC profiles after publicising.
People who do not understanding that very fact and publicising fakes 
should IMO be blamed for. They wanted free licenses and now as they have 
them, its time to take responsibility.
