The European Union last year unveiled tough draft rules targeting tech giants like Apple, Google, Amazon and Facebook that could shake up the way Big Tech does business.

Cook, speaking at the VivaTech convention for startups in Paris, took aim at some of the rules that target online “gatekeepers” such as Apple which controls which apps can be installed on its phones and tablets.

He said current proposals “would force side loading on the iPhone, and so this will be an alternative way of getting apps onto the iPhone.”
