Then a different approach is needed. One idea I can think of is to
come up with a set of both simple and complex objectives, and then see
which databases yield the best results. I believe this type of testing
would reveal more useful results for someone who's faced with the task of
choosing the right database engine for the job.

Unfortunately this is what happens whenever we compare Apples to
Oranges. Let's refrain from bringing Bananas into this. ;-D

They can do this regardless of what statements are made. In fact,
they could even take issue with something completely irrelevant and,
although the courts may laugh it out of the courtroom, it could be very
much like a DoS attack, but I doubt MySQL would be so bold since it would
likely be portrayed as bad publicity from the anti-corporation types who
seem to be quite easy to find in just about every open source community.

In that case MySQL could be in a lot of legal trouble in the future
given this web page where they include comparisons with database engine
products from various vendors (e.g., Microsoft, Oracle, SyBase, etc.):

Not everyone is hell-bent on brand names when it comes to determining
which products best fit the job at hand.
