If none of that freaks you out, then I have one word for you: Oracle.
This to me smacks of FUD.
Oracle, evil and terrible as they are, would have a very hard time killing or otherwise harming MySQL due to the code being GPL'd and the vibrant MySQL community (Percona, Facebook, Twitter, Drizzle, MariaDB, SkySQL, etc) that fixes bugs, adds features, and directly competes with the work Oracle does.
