The only question that I have, will it break my old devices, so they would be forced out of the iMessages ecosystem? I believe that would happen. I don’t use it heavily, but that’s one of the reasons I keep an iPhone these days. The other reason is FaceTime support, so I could easily connect with those with iPhones. I do use not very modern iPhones (the very first SE currently), as that’s what I need my iPhones for: to make a call (via FaceTime most times) and to send a message (via iMessage, sometimes). If Apple breaks that for me, I’m either forced to buy a newer iPhone (which I’m not sure I want, considering I’m all in Linux and Android). Or they force me to rethink my priorities and just leave this. I can live with that, it’s just less convenient.
