For example, Apple said it had had to delay certain features, such as live translation via its AirPods, to make sure they complied with the DMA’s requirement for “interoperability.” The EU rules specify that apps and devices made by one company need to work with those made by competitors.

Apple realizes that compliance with law takes time and is mandatory as opposed to optional. In other news, grass is green (when watered, anyway).

The DMA requirements basically come down to "don't be an anticompetitive PoS that manufactures e-waste" which of course ruffles their feathers since that's their entire business model.
