I understand all the downsides of RCS. I am not saying I will drop everything and proudly use RCS, but the fact of the matter is it is a massive improvement over SMS in terms of privacy and security and just quality. I want to know how I will be able to do this using Google’s Messages app on a currently deGoogled phone running GrapheneOS, while providing the least amount of data possible (ideally would like to avoid installing sandboxed Google Play services)
