That's not the point.
The question isn't whether they buy *Oracle* or not, as the sales
figures obviously indicate that they do.
The question is whether or not the actually get the 10 things that you
named.
I don't expect that they actually get all 10 of them, nor that they
get particularly close to getting all 10 of them.

I can't comment on that usefully.

Fortunately for sales, perception is much more important than reality.
The customers may not be *getting* better or more-quickly-available
security patches, but if they feel more comfortable, they may be
happier.

It's not evident that "encrypting code" actually provides security.
In order for the code to *run*, any encryption keys need to reside
some place accessible by the server, which therefore implies that the
keys are accessible to operations staff.
This is a common problem with the use of encryption.

Is this truly a security hole?
It is not at all evident to me that this indicates a security hole,
and simply asserting this to be so does not make it so.

SCO *lost* their case, and got slapped down plenty hard enough by
people intent on doing so that SCO no longer represents any sort of
example, aside from being an example that "in the Land of the
Litigious, anyone with deep pockets can potentially sue anyone over
anything," which isn't useful guidance.
You haven't pointed to any case law.

And you can't prove it without breaking contracts that were signed
promising not to publish results, so you don't have any *useful*
proof.

Stone tablets have been around longer than MVCC, but that's not an
example of anything.

You set a much higher bar than that. You claimed it was best, oldest,

It's *ALL* about perception, indeed. All 10 items you mention are, to
the extent that they are *perceived* to be true, a victory of
perception over reality.

There's the old tale of the "lady of the evening" who offered to "do
anything" for $100, and the gentleman in question said, "Great! My
house needs painting!"
Unfortunately, "do anything" has some questionable ethical
implications, and "hookers and blow" *do* lie down that road :-(.

100% agreed.
But we're not sales people, so we're not overly interested in that
reality.
We're much more interested in the technical realities.
