Apple is being sued for programming some iPhones to slow down when the battery gets discharged or gets old.

Ethically, this situation is complicated. Apple says it slows the phones so that they won't shut down unexpectedly. That, in and of itself, does not seem wrong to me.

However, the real fix for the problem of failing batteries is to replace them. It could be that Apple chose to slow down the phones so as to cover up the problem and avoid replacing them. That would be wrong.

There is also the ethical question of whether it is legitimate to build phones with batteries that can't be replaced — or removed, for privacy.
