> Icon in the Public Domain.
You can't re-create an icon to circumvent trademark law.
Using icon to refer to an application is fair use.
I am not sure what's the point of having a public domain icon.
Who's re-creating an icon? I can only see links to images from Wikipedia
Think of the fact that nobody working on the project even considered that as a helpful warning to not use it.
Even more humorous is the fact they decided to repeat this blunder under every single icon instead of neatly below the table.
