To be fair, I think if Facebook were starting over today with a clean codebase, and know they were going to grow into such a massive enterprise, they might have made different design choices. As it is, they are committed to MySQL and have tuned, optimized and tweaked the hell out of it to suite their requirements.
I believe a Facebook engineer once stated exactly what you suggest. I'm sure they would have gone another direction but just the fact that Facebook is able to use it like it does seems to imply it's a pretty capable open source project, despite its flaws.
In reality, MySQL is sort of a poster child for open source software. It's a case where a company started using it to keep expenses down. Out grew it but because they had the source they were able to modify it for their use and contributed it back to the community. I can't think of a better example really.
