outside of the imperium center, you'd be lucky to have one provider of some product or service. and usually they will only be reachable via whatsapp. because metabook used whatsbook as a backdoor for for their failed oneinternet(?) project.
remember the backlash fb got when they offered free internet in india and africa but only for the Facebook app?
well, everywhere in the world you get free whatsapp traffic, so everyone now is on whatsapp.
good luck convincing a business who get hundreds of sales call via WhatsApp tobuse signal.
or convincing people who can barely afford their water bill that they now need a data plan to use signal instead of free whatsapp.
They won on distributing E2EE and the Signal Protocol to 99% of the world, which previously transmitted everything in plain? Sounds like a pretty good win to me.
