Motivations and incentives are a very big and important aspect which
is often overlooked in large scale projects.

For example, one of the really big problems with device drivers in the
embedded space is that the team that works on SOC version X gets
disbanded, and immediately reassigned to SOC verison X+1, sometimes
before product has even shipped.  Having one device driver that works
for SOC versions N, N+1, N+2, ... N+5, is really important from a
maintainability and being able to send out bug fixes for security
flaws.  However, it means that whenever you make changes, you need to
test on N different older versions.  And between the need to release
product quickly, and the fact that engineers are !@#@! expensive, and
the teams constantly getting formed and reformed, it's much easier to
do code reuse by copying, and so you have N different versions of a
device driver in a Board Support Package version of the Linux kernel
shipping by a SOC vendor.

Unfortunately, I have to disagree with Larry, there are many, many
engineers who works because they get a paycheck, and so they go home
at 5pm.  Some people might be free to improve their code on their own
time, or late at night, but corporation also preach "work/life
balance" --- and then don't fund time for making code long-term
maintainable or reducing tech debt.

Open source helps because embarassment can be a great motivator, but
more important are the fact that there are people who are empowered to
say "no" who don't work for the corporation who is trying to cut
corners, and who have a higher allegiance to the codebase than their
employer.

There is a similar related issue around publishing papers to document
great ideas.  This takes time away from product development, and it
used to be that Sun was really prolific at documenting their technical
innovations at conferences like Usenix.  Over time, the academic
traditions started dying off, and managers who came from that
tradition moved on, retired, or got promoted beyond the point where
they could encourage engineers to do that work.  And it wasn't just at
Sun; I was working at IBM when IBM decided to take away the (de
minimus) bonus for publishing papers at conferences.  But at the
Usenix board, I remember looking at a chart of the declining number of
ATC papers coming from industry over time.   And it was very depressing...

And the key for all of this is motivation and incentives, as any good
historian will tell you.  This is true whether probing the start of
wars, or the decline of a technical community or tradition.
