Rosti's comment about an "independent international governing body" leads to another point:
Mr. Pajitnov and Mr. Rogers want Tetris to become a sport at least comparable to tennis (after which Tetris is named). But as long as The Tetris Company exercises its exclusive right in arranging Tetriminos into horizontal rows, this will not come about.
Nobody needs permission from
The Tennis Company to manufacture equipment for recreational tennis. Nobody needs permission from
The Chess Company to build a chess set, and FIDE takes no legal action against the play of
variant games. Cross-training exercises done with homemade equipment that is not tournament legal can make players stronger. Tetris, on the other hand, relies on one supplier. Cross-training was the explicit goal of some fan games, but the recent ruling that fan games infringe copyright endangers this. Even StarCraft, another proprietary game seen as a sport in Korea, allows for creation of mods as training tools. What Tetris product has such modding tools? That's one reason why I don't see Tetris becoming a sport equal to even StarCraft within the next seven decades.
I used to play StarCraft.
