There's a post here: https://www.apple.com/newsroom/2026/06/due-to-dma-siri-ai-de...

Take it with a grain of salt but I don't think it's other AI providers that Apple is upset about. The DMA would require users to be able install any openclaw like thing onto their device with access to everything that Siri can access today. There are all sorts of arguments to be made here but I can understand why Apple feels this way and wants to offer a good experience here.
