Diglet reports that the family of Joan Miro and the Artists Rights Society asked Google to take down the Miro-esque logo that Google created to celebrate the artist's birthday. Google quickly complied.
Now, I don't know if Google's logo violated the artist's moral rights, but I do know that many people look at that logo and then follow-up to see who or what is being honored on the day of a special logo. It is likely that many, many more people became aware of Joan Miro on April 20 because of the logo. I know that doesn't make doing something Fair Use, but it is sad that the Artists Rights Society couldn't see the benefit and perhaps find a way to work with Google to help the company find an acceptable middle-ground that it can use in the future.
