MySQL mistake is a wake-up call on open source ownership

There was a moment of panic in the open source community this week when a developer on the MariaDB fork of MySQL discovered that Oracle had quietly changed the license on all the main pages for MySQL from GPL to a restrictive proprietary license two months earlier. Prompted by the bug report, Oracle’s staff quickly discovered that an error had been made in the build system and promised to immediately undo the change and restore the GPL to all of MySQL. Problem solved!
