Ah...so 'twist' is right because he has 3000 comments, and Grayhaze is wrong because he's only a professional and has 50 comments.
There's total logic in a nutshell.
Perhaps Neowin is being a bit too insular...certainly some of its members are.
Twist, you are a prat...and you are wrong.
The image of the icon set is to look at, which, by necessity of the methodology used, must be cached onto your harddrive.
THAT is its intended use, and therefore is the limit of its legal copyright use.
Removing it from your temp file/cache and modifying it as a stand-alone icon is beyond that limit and therefore abuse of copyright.
However...
No MATERIAL harm is done by doing this, so it would be highly unlikely to be pursued.
Were you to pass that 'icon' to a third person, THEN you would be in trouble.
In fact, the example image displayed in the thread IS a copyright issue 'just maybe' protected by 'fair use', as it is for 'educational example'.
Bugs me when pseudo experts spout crap.
Leave it to the real ones...
