The prognosis is much less grim than it once might have been for MySQL, in the wake of Sun being bought out by rival database company Oracle. Monty Widenius, who is to MySQL what Linus Torvalds is to Linux, has founded the Open Database Alliance with a handful of MySQL-based companies, in a move that will insure against any Oracle underhandedness that might come up (though that is obviously not their stated goal).
These are the guys you’re going to look to for a fork of MySQL, if Oracle decides to squash it. And that is the beauty of open source software. No matter the intentions of a business toward a piece of software, that software will live on.
