In the future, spare parts will no longer connect mechanically but also digitally, requiring the part and the system to perform a cryptographic handshake. If you make a part that's "unofficial" and reverse-engineer the connection, the OEM could argue you are in violation of DMCA's DRM clause. For example, think of printer ink, or phone batteries, car tires, anything replaceable, really.
