Oracle is paving the way to turn MySQL into (essentially) SQL Server Express: a free hobbled version of an otherwise commercial database, designed to do one thing and one thing only: pressure existing MySQL developers into moving to (and paying for) a commercial Oracle license. MySQL is nothing more than an onramp to Oracle. This was obvious when Sun was acquired. It's obvious now. Every word I've heard from Oracle regarding MySQL confirms this.
This is what Oracle means by "integration".
You think the number one commercial database provider in the world is going to help build and improve a free, robust, industrial strength database for the good of the open source community? Like they could care less whether you use a free DB or shell out for an Oracle license? Please. Oracle sees MySQL as a huge potential market, nothing more. And this is how the evisceration begins.
