True but Supercell's issue is that they are frequently changing things.
Their official stance is that they don't give out the info that the wiki contains because they don't want to say one thing and the next day do another. Also the players' capacity to write articles detailing various aspects of the game greatly outstrips Supercell's ability to do so. After all the game has millions of players. No way would Supercell have content like Flammy's strategy guides. The wiki itself has 1000's of images and currently 20 staff members. There are also efforts underway to translate the wiki into different languages.
Despite Supercell's lack of involvement I think the wiki is a pretty accurate and valuable resource when jerks aren't vandalizing it. The staff is pretty good about rolling back most instances of it as well, but sometimes things such as this slip through.
