Actually I never used MySQL really. But sometimes it's great to know why decisions are made. Actually I don't think they said, "well lets use MySQL over Oracle" especially since MySQL is a Oracle product, too. There would've been a way to use MariaDB aswell. And I guess anything with license costs fall out already (they explained why in the article). Edit: My guess would be that they still keep galera in mind, but since they didn't shared they why, one could only guess. And Transaction Wraparound maybe.
