Grigore,
I agree- no tool is immune. But it is difficult to criticise somebody for choosing a Microsoft or Oracle product. Too many mySQL "bugs" will make sysops start thinking about that carefully, even if the other options have as many or more problems.

"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
