In your hypothetical, if Apple, Inc. owned copyright over the particular
code they released under TGPPL, what exactly _would_ oblige them to
comply with the TGPPL disclosure terms after 12 months?

To explain:  Were that code copyright, by contrast, held by some other
party, Apple would commit the tort of copyright violation against that
party, by redistributing his/her code without complying with his/her
conditions -- but Apple, Inc. cannot be held to violate their _own_

So, what does 'had to' mean in this context?  Or else what?
