Some say throttling.
Others say the system stays running until you can have the battery serviced.
You are right. Lots of opinions and people taking action without learning the physics and basics. If Apple had been more open what was happening sooner, the lawsuit might not have succeeded to reach class-action status, but laws arecan be horribly flawed (slavery, death sentences, chopping off fingers or hands for instance). In the US pretty much anyone can sue and sometimes settling is smart to avoid risk of an adverse finding and not an admission or merit or guilt.
