[1] badly misrepresents what happened. Throttling peak performance when the battery can’t deliver enough power for it helps people use the phone longer. It’s almost the opposite of planned obsolescence. The alternative is people’s phone shuts down randomly, which is definitely more likely to push them into replacing it. It also is fixed after the battery is replaced.

Unless you mean that the battery gettin old is planned obsolescence. But that’s not a great arguement either. Batteries are a wear item, and will need to be replaced if you want to use the device more than a couple years.
