It was shit already because Samsung's VoLTE has been proprietary for many years. Buy a modern Samsung, unlock the bootloader, install a ROM: say goodbye to the ability to communicate easily. Do people really want this? I'd love a modern device running lineageos or /e/os with everything working but the manufacturers are determined that this cannot happen, and they own the hardware even after you bought it. My main phone is Samsung & runs stock, unrooted, unmodified. Why? So I can fucking use it! My backup is an old Moto G7 Plus. It runs /e/OS beautifully and I can even run my bank app on it. But I cannot run Google Wallet so cannot use it to pay or identify. This is crucial. Money, trade and exchange are not secondary but at the root of human behaviour.
