The team of MobileTetris was forced to change their name because of using the copyrighted name “Tetris” in their product.

We love you, DMCA. Please, everyone, take a second to drop Senator Orrin Hatch a line. He made this all possible. (He’s my home state Senator.) (Note: I respect copyright. I don’t mind being asked to change the name. I do, however, mind when it comes under a blanket threatening law like the DMCA, which is unnervingly broad.) Senator Hatch, you will never get my vote.
