Closed source doesn't stop copycats.  They can hook up logic analysers
and see how the hardware works.  They can pull apart boards and work out
the wiring and parts.  They can decompile software and firmware, to
discover its operating principles.  They may not make a perfect clone,
but they may have discovered all the tricks that the original
manufacturer made, to make their own similar product that works just as
well, or even better.

Just about all electronic devices are open source, so to speak.  There's
nothing really secret about how a television set works, even a
particular model.  Likewise for a personal stereo system, or a telephone
exchange.  Yet none of those devices have their sales killed.  They even
benefit from being able to check on each other, and avoid dumb ideas.

All closed source does it make it more difficult for someone to work on
without all the toys that I talked about in the first paragraph.  I
think the wealth of what can be done with open source on Linux, and
other OSs, does demonstrate why it's good.

But doing this takes time and allows a company some time to market their product and make some money from it.

Of course if you reverse engineer a product, you could open yourself to legal headaches in the USA due to the DMCA.

Due to the move to M$ Exchange Server,
   anything that is a priority, please phone.
