When someone sells you something (e.g., a phonograph, or phonograph
recording)
they can claim that the warrantee is void [1] if you use other than
*their* parts
(phonograph needles, licensed phonographs), but they cannot tell the
govt that they
are harmed by your use of unapproved gear.
The DCMA folks need to understand this. Badly.
[1] An OEM may not be always be able to void a warrantee for objectively
bogus reasons,
e.g., a car manufacturer probably couldn't get away with dropping a
drive-train warrantee
because you used generic oil that fullfilled published specs.
