The image is placed in the infobox at the top of the article discussing Infobox, a subject of public interest. The significance of the logo is to help the reader identify the organization, assure the readers that they have reached the right article containing critical commentary about the organization, and illustrate the organization's intended branding message in a way that words alone could not convey.

Because it is a non-free logo, there is almost certainly no free representation. Any substitute that is not a derivative work would fail to convey the meaning intended, would tarnish or misrepresent its image, or would fail its purpose of identification or commentary.

Use of the logo in the article complies with Wikipedia non-free content policy, logo guidelines, and fair use under United States copyright law as described above.
