Oracle is great for MySQL's development :: one thing I've noticed since MySQL 5.5 – it's of much better quality than the previous versions. A lot of very important features, especially related to InnoDB, are released. 

MySQL 5.6 provides even more excellent features for us.

That's why I think Oracle is making MySQL into a much better product. I'm happy for the MySQL users everywhere.

However, Oracle is starting to close MySQL. Parts of MySQL that's very important to the open source community have begun to be closed down : http://blog.mariadb.org/disappearing-test-cases/

I understand that Oracle feels confident about its ability to develop a superior product. But moves like this causes fear with people, such as "what's next to be gone missing – MySQL's source code ?"

MySQL can become a superior product because of its community. Even giants, like Google, Facebook, Percona, etc; are contributing very important patches to it. If Oracle closes down MySQL, then MySQL will suffer from it.

So, yeah, Oracle is great for MySQL's development. Not so great for its community.

If you're looking for a MySQL-compatible database with great community backing it, then it's simple: MariaDB.

For anyone looking for comparison between MariaBD & MySQL, hope you'll find this useful.
