Y'know what, I'd have no problem paying for my "core services" if it were that easy. What I have a problem with is paying for potentially so many services:
* phone
* whatsapp, because others use it
* signal, because it's actually good
* telegram, because that one group is on it
* my todo list app
* duolingo
* a good mapping app without ads
... and so on. And the same for my kids. And before you blink, you suddenly pay several hundred dollars per month.
Aka the slippery slope.
One of the problems seems to be that everything comes with transaction costs, so for example Signal cannot easily charge me a single dollar per month, which I suspect is a price point that would work for both me and them (if every one of their users paid it).
