> so-called "linking exception", that releases MySQL under the Apache Software License 2.0, an open source license

The author failed to note that MySQL is already free software under the GPL. Monty just wants to make another proprietary fork. At this point I'm surprised Sun hasn't sent lawyers after him for trying to damage the asset he just sold them.

Summary: After selling MySQL for $1billion, Monty would like to have access to the code again to build another business off it.
