As someone who has profited greatly from this, I must point out that
he is correct.  I've profited both from the fact that during and after
the lawsuit there is a great, _and artificially created_, shortage of
technical talent, and the fact that companies will indeed shoot
themselves in the foot by automating existing processes rather than
reengineering them, if having the source code allows them to do so. 
And when it gets obsolete and no young 'uns want to deal with it,
that's when the big bucks begin.

New or old, they get old or they die horribly.  Until there is some
desire in the industry for stability over time, this is a red herring.

Make buckets o' cash following them, too.

Not necessarily.  I've seen plenty of "design drift," especially over
time when the newbies may not have the context of the original
developers, and the managers feel the need to compete with completely
different things from competitors.  There is also the classic case of
developers going from place to place because they are only interested
in new stuff, so follow-on developers miss a lot of the organizational
wisdom.

Well, this is double-edged.  As someone who has spent a great deal of
the last couple of decades dealing with heterogenousity, I can state
with some confidence that the lowest-common-denominator approach will
make it very easy for the competition to eat your lunch after you've
created their market.  I think SAP has seen this and that is why they
are so hot on controlling mysql, and I think Oracle has seen this and
that is why they are so hot on controlling peoplesoft (they scheduled
the court date for September IIRC?), and I think MS has seen this, and
I think everyone else has seen that MS has seen this, and all the low
to midrange enterprise app competition are already going under.  Niche
markets excepted, but perhaps even more sensitive to LCD.

If you use non-standard features, your wrapper has to emulate it for
those db's that don't have it.  This may well be rocket science you
are reinventing.  I've seen it be a problem over and over.

OK, give me the source to the Redhat 5 tape driver.

It's so funny, because I've heard it.  And at one time, I almost
actually said it.  I did once say something like "I'm not coming in
while my wife is having a baby merely because your 'lead dba' can't
follow instructions to load a test database."
