Also as a note here, if linking implied derivation, then all software
that ran on Windows would be illegal to distribute without Microsoft's
permission...... Yet at least here in the US, jailbreaking an iPhone
is legal in the opinion of the Copyright Office because it allows fair
use of the device, namely installing apps that Apple hasn't otherwise
authorized. So I'd generally agree with the assessment above.
