Well, I am probably going to draw flames about this since I am not writing
commercial applications (yet), however...

I wish that the code protection fuse didn't exist.  Why?

If someone wants to bad enough they are always going to find a way around
it.

So, someone from a country that is notorious for stealing software and
hardware designs manages to bypass the code fuse for your product.  They
manufacture your product, but since they didn't have the R&D they can
undercut you and you are hosed.

Because of the code protection fuse you can't read their code.  Is your
company going to invest in bypassing the code fuse, probably not unless they
have a good idea of what is going on.  You are hosed.

Without the fuse?  Well, you do a quick dump of the code, compare it to
yours, and the lawyers get to make money.

I, for one, don't believe that any of the manufacturers have a foolproof
method to keep someone from looking at your code.  Maybe I'm clueless.
