They’re only switching because they were made to.If Apple cared about the environment and e-waste as they claim they do, instead of releasing a new USB-C case they could have just released a 10$ USB-C female to Lightening male adapter. This could have solved this “problem” for all devices still using Lightening plugs.
I mean, this could be a universal one-fits-all solution, instead of making zillions of new cases for AirPods that have a 2-3 years lifespan anyway, then their built-in batteries degrade.
