The standoff centers on the Digital Markets Act, the E.U. law that requires major tech platforms to give rivals equal access to their systems. At the center of Apple's complaint is its contention that Brussels' reading of the DMA would mandate that any competing voice assistant receive the same deep system-level permissions as Siri AI — permissions that would encompass messaging, purchases, file access, and cross-app actions — with none of the privacy and security guardrails the company considers indispensable. To bridge the gap, Apple put forward a proposal called Trusted System Agent — a go-between layer intended to give rival assistants comparable access to Siri AI's capabilities — paired with a plan to phase in that solution across an 18-month window. The Commission rejected that plan along with all other proposals Apple submitted, the company said.
