He told us so!
Anyone who works in or with software knows the danger of a product/project being orphaned: left unsupported, and its users in limbo, facing forced migration to something else. It is a strong argument in favour of open source: if you have the source, then if the worst happens and your supplier/support organisation disappears, or is bought up by someone hostile to it, you can hire someone else to maintain it.
My Apache colleague Gianugo Rabellino (one of the most interesting thinkers and inspiring speakers anywhere in the FOSS world) has argued for years that open source alone is necessary but not really sufficient, and for a product, you need open development. This evening he’s one of the many bloggers to comment on the Oracle acquisition of Sun, and argues there is now a danger of MySQL being orphaned and its users left in limbo despite MySQL being open source (GPL)! His thesis (here) is that if Oracle wants to stifle MySQL, they can make it very unrewarding for anyone else to pick up development.
I don’t think his point completely stands. If enough of the original/current MySQL team were to leave Oracle en masse, they could pick up development, and make a support business of it on the basis of their reputation, in spite of not owning the IP. But that’s not a nice scenario, compared to MySQL as an independent or within Sun. Or of course within a supportive Oracle.
On the subject of MySQL itself, I’m more optimistic (albeit through the perspective of benefit of the doubt – I want this to be good). While acknowledging the danger, I’m sure Oracle can see the business case for maintaining a healthy MySQL product and community. LAMP and other FOSS users are not short of credible alternatives: obvious candidates include PostgreSQL for serious applications or SQLite for lightweight php-ish stuff, and if MySQL loses its bloom, they’ll migrate. Surely better for Oracle to keep them on-side, make tiny margins on LAMP business and support, but gain a serious market from those who grow big and might be sold a smooth upgrade to a top-end platform where Solaris and Oracle replace Linux and MySQL.
 What’s MySQL’s current market share? Is it more than all other SQL databases combined?
