I think your rant is justified. Perhaps this device has a
manufacturing error which began after it was approved? Isn't there
some way you could submit a complaint to the approval authority
yourself? Maybe even anonymously if you are concerned about it getting
back to your "senior being"?

I am curious, though: what is a CD monitor? I tried to google it but
that's a bit tough given that CD is such a common acronym.
