Oracle moves Mysql towards closed source software as it held back test cases in the latest release of the popular RDBMS. This means that, even though there are some bug fixes in the releas, there is no assurance for the developers as there are no test cases for the reported bugs.

This is only the latest move Oracle makes in alienating the community. OpenOffice lost its foothold after large part of its maintainers decided to fork it and create LibreOffice. As for mysql, it has already been forked to MariaDB, which is one of the recommendations for its users.
