Tim Cook is not a fan of Rich Communication Services (RCS). The Apple CEO made this clear at the Code 2022 conference, when an audience member asked Apple to adopt RCS so his mother could better see the videos he sends, Cook told him, “Buy your mom an iPhone.”

For the uninitiated, RCS is like hypercharged SMS that lets you send high-quality multimedia files like other chat apps such as WhatsApp and Telegram, while also providing now-standard messaging features like typing indicators, delivery and read receipts, among other things.
