If you bought the cheap welder and opened it up and twiddled it to make it as good as the more expensive one then that is fine and totally lawful. (And there have been a fair number of products intentionally differentiated that way: someone willing to move a jumper gets the premium product, but lots of buyers will just pay)<p>The complaint about the DMCA is that it gives a trivial distinction which many users could presumably self-upgrade otherwise the force of law.
