I ran across this article: IBM, MS reject MySQL
from a InfoWorld e-letter and thought others might find it interesting. I wonder if the fact that both companies have their own database products has anything to do with it? Sun and Yahoo on the other hand had more favorable things to say.
Granted MySQL is not for everyone, but some of the statements made are both vague and ludicrous. I leave you with a quote by a MS manager:
With open-source, you're not going to get a platform that's as reliable or scalable or as secure as what you're going to get with a leading vendor, . . .
Update: For those curious about the PostgreSQL Great Bridge angle.
