@neiljhaveri been a great fan of Mimestream since its earliest days and am looking forward to the iOS beta when it appears. :)
What will actually happen, I believe, is that E2EE messaging platforms like WhatsApp (overwhelmingly popular in the U.K.), Signal, and iMessage *will stop working and be pulled from app stores in the U.K.*, full stop. The U.K. seems to think it’s a bluff; I don’t.
