Yes, that and being unable to modify a printer because the code was closed

At the time there was something of a racket in which people would take
millions of dollars in US govt. grants to build software systems that would
then be claimed as proprietary property. That was one of the issues that
Gates agreed was problematic.

Getting back to security, one of the majort changes with managed code is
that unless deliberate steps are taken to obfusticate, decompilation is
fairly straghtforward.

Having source code seems to me to be a 1990s level concern. Having source
is good but not enough. The biggest problem I have is knowing provenance,
is the code I am going to run the code I intend to run. Does the compiled
match the source.

Using the CLR approach provides the opportunity to optimize to the specific
platform with only one executable to sign.
