Up until sometime in the mid-80's, source code and hardware schematics
were a standard part of the documentation all customers received with
computers.  IBM was just following their standard practice.  Remember,
up until PCs became widespread, computer operators were expected to be
able to read the schematics and source code.  I'm sure there are plenty
of people on this list who remember having schematics with their 11/780s
and PDP-11s, and remember having the source code to IBM's VM on

The kind of open documentation that I think everyone on this list would
like to see was at one time very common.  It was also very hard to copy
the hardware.  It required a huge investment and so only a few companies
could attempt it.  IBM could go after those few companies with patent
and/or copyright infringement lawsuits and control the competition.

The software wasn't any good without the hardware, and since the
hardware was easily controlled, there wasn't much need for software

Enter the era of the PC.  Virtually anyone could buy the off-the-shelf
parts to build a PC.  Anyone remember building a PC from Heathkit?  The
hardware became easy to clone.  "Computer operators" became "users" and
no longer had to have electrical engineering degrees.  Only a very small
percentage of computer owners now cared about the schematics, but the
schematics were incredibly useful to the clone makers.  So schematics
went away.  (Once IBM realized what they had done, they tried to put the
genie back in the bottle by releasing a new hardware architecture that
they controlled: MCA.  But by then it was too late.)

Companies could no longer control the software by controlling the
hardware.  A company's software was now useful without its hardware; you
could run it on clone hardware.  Hence, software piracy was meaningful
and companies put controls on their software too.  No more source code

This is, of course, a highly simplified view of history.  Many people
forget is that it was once common to get source code, and that the IBM
PC was a major catalyst for closed source.
