While agree the focus metaphor isn't a great one but you are also miss-selling the Tesla situation here. Tesla restricts your battery usage for battery life purposes. This allows them to sell you a vehicle that has a charge matching what they claim while also having a battery life matching what they want it to be. SSDs work similarly. You don't sell 1 TB of SSD storage you sell slightly more than 1 TB worth. Then you wear level between cells to ensure the whole thing lasts a lot longer. (Batteries are nice because losing a cell isn't losing data but the fundamental strategy isn't anti-consumer)
