If they see it as a metaphor instead of whar it is that still makes it fundamentally ignorance.

Remember "a series of tubes" memes long predating youtube or its many pornographic not-quite-competitors?

It may map to better understanding but it is still ignorant as somebody software proposing applying computer antivirus software style scanning to infectious disease gene scanning of all micro-organisms in the body.

Even if the metaphor is technically correct in some aspects (the microbes being unauthorized executables in a space) the differences are substantial enough that it cannot be called anything but ignorant by those in the know who would point out precisely the current limitations and theoretical impossibilities like "we can't read cell DNA without destroying them currently". In the case of the safe analogy it is essentially impossible for someone to wind up ordered to open a random piece of garbage that is indistinguishable from a safe. Unlike with encryption.
