They all have iPhones and Google Android. Since all my calls and text messages are monitored on their phones, am I causing any additional harm to myself by using Google Messages on GrapheneOS? That way I could at least use RCS messaging.
From my point of view switching from a proprietary application to a free application is always a gain. You can’t control what other people use, but you can take steps to reclaim your own freedom and control.
It’s unfortunate there’s no way to use RCS from a free application, though.
