You're not understanding the issue here. This had nothing to do with how fast the battery degrades. This was only ever about how the phone acts with an already degraded battery. The two choices are 1. Shut off the phone suddenly if any high performance tasks are attempted 2. Throttle the phone performance to keep it from shutting off.
Apple chose #2, which is best for customers, and got forced to pay $113M from it. It's ridiculous.
