Right, once you get into large million-dollar+ companies, they won't use the free stuff because of its lack of polish as a corporate solution such as Oracle. I believe the going rate for Oracle software is in the $20,000 range. Oracle is something like 100x faster than MySQL. When you are dealing with corporate web sites that are doing 100s of queries a minute, the server has to be able to handle the load. MySQL starts to degrade, and fail.
