No there is no truth in what u heard, from my experience. Called em to find out what their blade inventory was because I was thinking of shipping blades to neutered country, for thinning by excellent craftsman. The risk is that governance will take the blades, so I needed to know which ones and my cost if they "disappeared." BMC answered the phone quickly, and completely met my needs, walking through my list with me. With their info, I did not send my regular production / exclusives blades for service that I could not replace. I think there may be, or was, a different set of rules for knife blades bought from configurator. Maybe someone will pipe up, or you could search this forum or just call em.
