Ship of Theseus. If you replace every single human at Apple with someone different, it's still Apple. Apple is, at this point, a separate entity, under control by a given group of humans at a given time, but that can change.

The problem is considering "Apple" itself a person, as corporate personhood does. Thinking of companies, even in limited contexts, as a "person" allows the individuals actually making decisions to be largely immune from liability on a personal level. Maybe that should change.
