Tim Cook doesn't like Rich Communication Services. Cook told the audience member that his mother would be better off if she saw the videos he sent her.

For those who don't know, RCS is similar to hyper charged SMS that lets you send high-quality multimedia files like other chat apps, while also providing now-standard messaging features like typing indicators, delivery and read receipts.

Blue and green bubbles for other text messages have been the subject of debate for a long time. The bubble war would end forever if Rich Communication Services were adopted by Apple. Recently, it launched a new campaign in an attempt to sway consumer sentiment to its side of the argument.

It is not about the color of the bubbles, according to the website. The blurry videos, broken group chats, missing read receipts and typing indicators are some of the things that make up it. Modern texting standards are not adopted by Apple when people text each other.

More than 500 million people use the messaging app on their phone.

Cook said Apple customers didn't want this support. Cook said "I don't hear our users asking that we put a lot of energy in on that at the moment."

Customers have turned to third-party solutions over built-in clients due to the fact that the issue of different bubbles doesn't exist if you use other messaging apps. Many iPhone owners still use iMessage as their preferred chat app, despite the fact that first-party solutions still have a draw. Keeping a closed iMessage system encourages people to buy iPhones as they don't want to end up as the green bubble in their group chats
