The reason to do this is the markup on mil-spec parts. I am working with a TI DSP, it costs around $8 for the commercial version, around $30 for the "Enhanced Plastic" version that goes from -55 to +125, and about $300 for the full spec part in a ceramic package. The availability is often low on mil-spec stuff, so that also plays into it - people will pay a premium to not wait 20 weeks for a production order to come through.
It must be really cheap to remark things. I've run across counterfeit MOSFETS - the original part was only $0.50, but were in short supply. Purchasing bought some through a 'broker' (pretty much scumbags as far as I can tell).
We kept blowing them up, and finally sent some off for failure analysis. The xray showed the replacement part was totally different and only had one bond wire in places where the real part had 3.
