With respect, this is madness.
A huge number of products are sold second-hand via Craigslist and eBay. Contact is minimal and steps taken are almost always limited to the bare essentials i.e. buy, pay and ship.
Asking the previous owner to un-jump through a set of hoops so that the new owner can jump through a second set is as time-consuming as it is unproductive and in many cases the prospect of an mostly-anonymous seller doing so in a timely fashion is a pipe dream.
The objective here is to gain access to the software updates. If the user is taking the initiative to do so, why is he asked to navigate some Byzantine process? 99% of products in the music trade or in technology in general make software updates readily available. Capturing sale data for marketing purposes may appeal to internal staff but to the user base it's simply red tape.
