Apple is restructuring its App Store division, splitting it into two teams following new EU regulations that require the company to allow alternative app marketplaces. Matt Fischer, who has led the App Store since 2010, will depart the company in October after 21 years, marking a significant leadership change. Carson Oliver will oversee the traditional App Store operations, while Ann Thai will lead the newly formed team responsible for alternative app distribution. This restructuring aims to address regulatory pressures and enhance competition among app stores. Fischer expressed pride in the App Store's growth and thanked his colleagues in an email announcing his departure. The changes come at a time when Apple faces scrutiny over its app marketplace practices and ongoing legal challenges.
