From over at Homotron: Tris, a Tetris clone that currently holds the top spot for free iPhone apps on the App Store, is being pulled tomorrow due to a copyright claim from the Tetris Company, which the developer can't fight off:
The trouble is, I'm a college student, and not an affluent one, and I simply do not have the time, energy, or resources to fight this battle right now. There's a point at which I am willing to give up and be practical, to let the world have its way with that ever-mistreated little ideal of "principle". Thus, it's with great sadness that I must announce that I'll be pulling Tris from the App Store on Wednesday, August 27th, to remain in Apple's systems but publicly unavailable until I work out a solution to this.
