Unfortunately, at least in the U.S., most inter-OS text-messaging is still done via SMS. Signal was godsend in this field because I can slowly convince my network to switch to Signal (and this in turn had a recursive network effect as then they would do similarly). This change will mean Signal will become another bucket on my phone (along with WhatsApp) where I can talk to only a select few of my contacts.
