The bottom line: As both a community member of MySQL, and a service provider, I am not worried about Oracle buying Sun and acquiring MySQL in the process. There is no validity to the argument that Oracle will slow down or stop MySQL development — it is not possible, with various forks already in heavy development, and it is not probable, because Oracle has owned the InnoDB codebase for 4 years and has not slowed that development down.
