Right now, the only solution to this situation seems to be sticking to SMS and newer non-IP protocols extending and/or replacing it as a service offered in the regulated TelCo market (in EU at least, but practically in most places). Then mid-term extend regulations to IP- and web-based markets as well, forcing checks/balances, appeals, and an open ecosystem of alternative providers in place where there is feudalism right now. Won't work with FAANG providing services "for free"; that is, by bundling and ad-financed offerings. So bundling has to be regulated as well.
