One got jumped on by the Disney legal team for painting Disney characters. They were ordered to pay a royalty or paint the characters over. So they painted them over.
The new mural used Sanrio characters (Hello Kitty and such) since Sanrio was so pleased with the idea of having their characters on the wall, they even sent one of their artists to supervise the painting. The kids and their parents voted to move their annual outing from Tokyo Disneyland to Sanrio's Puroland amusement park. Last I heard, they never went back.
I wonder how much Disney's greed cost them?
The NFL’s legal department is simply trying to justify their existence. Among their jobs is protecting the NFL from trademark and copyright violations etc., and this does technically qualify as a violation of their broadcasting rights.
Of course, suing churches and little league teams is not exactly what the NFL Board or PR folk like to see, but like any huge and wealthy bureaucracy, there are factions that are pulling in different directions all the time.
