The point is mainly that offering these labels might grant us more photographs. Hence, with a very little concession to the standard to which professional photographers are accustomed, we could replace lots of "fair use" pictures with Free images, and illustrate articles which lack images.
But this clearly is far less funny than twisting words to expose suspicious language of a potentially anti-democratic nature, or than acertaining the purity of the ideology in which people contribute their images. It's not like we're making a project in the, you know, real word, is it ?
