Apple complained that requests from Meta Platforms requests for access to its operating software threaten user privacy, in a spat fueled by the European Union’s intensifying efforts to get the iPhone maker to open up to products from tech rivals. The EU’s executive Commission is drawing up “interoperability” guidelines for Apple under its new digital competition rulebook. The interoperability requirements would ensure devices like smartwatches or features like wireless file transfers work as smoothly with iPhones as do Apple Watches or AirDrop. In response, Apple said it’s concerned that some companies may attempt to abuse the provisions and singled out Meta, saying it has made multiple requests that would reduce privacy protections for users.
