Oracle, Sun, & MySQL
From Eben Moglen:
I believe that Oracle sees clearly the nature of its business interests. It knows that MySQL is much, much more valuable to it alive than dead. In fact, Oracle has almost as much reason to improve MySQL as it has to improve its flagship product. For a small firm, like MySQL AB, dual-licensing revenue was the only efficient revenue source with which to develop the product. But for Oracle, service revenue is much more significant than dual-licensing royalties. As all parties who have spoken about the merger agree, regardless of which side they are on, enterprises that use Oracle are very likely to use MySQL also, because MySQL is the world leader in number of installs. Which means that companies that pay Oracle to service Oracle are very likely to pay Oracle to service MySQL as well, if Oracle is not only servicing MySQL but acting as primary funder and participant in a flourishing MySQL ecology. Even if Oracle were only willing to invest in MySQL the extent of its ability to increase the MySQL service business, Oracle would be the best thing that ever ichappened to MySQL. In fact, Oracle has an immense incentive to invest far more in MySQL than the extent of its increased winnings in the MySQL service market. MySQL driven technologically and economically by Oracle will be a price-zero full-GPL missile aimed at Microsoft SQL Server.
