I think EA hold the rights to mobile versions only—the Tetris Company can still release on consoles and PC. Puyo Puyo Tetris and Tetris 99 on Switch are pretty good (the latter is by Arika and is actually superb) and Tetris Effect, designed by Tetsuya Miziguchi of Rez fame, is an incredible piece of work on PC.
I really, really like Tetris.
