There are five things that come to mind from the antitrust lawsuit against Apple

Apple has been accused by the US Department of Justice (DOJ) of unfairly limiting competitors like WhatsApp, Signal, and Facebook Messenger. The DOJ said Apple also limits third-party messaging apps like WhatsApp, Signal and Facebook Messenger in comparison to iMessage. It added that Apple doesn’t support RCS to make cross-platform messaging better and third-party apps would still be banned from incorporating it even after Apple adopts it.
