Open source uproar as MariaDB goes proprietary

Which is to say that MariaDB Corp (which is not the MariaDB Foundation, which handles development of the database), is attempting to monetize a new version of one of its products (but again, not the core database software, just a routing/load-balancing proxy), by making initial releases only available under a commercial license.

The title seems a little sensationalist, since "MariaDB goes proprietary" seems to imply that the actual database software is going to cost money, which it is most certainly not.
