It says something about Play Billing being used specifically to mitigate spam?

I understand using play payments initially but hopefully eventually there's a way to buy an account without going through google.

What about their built-in cryptocurrency? It's a perfect use for it. They could require payment post-install yet before message can be sent.

Ugh wtf so I need a Google account on Android? That's not going to happen.

For an org that pretends to care about privacy you'd imagine there'd be a way to avoid, you know, the biggest privacy invader on the planet.

Just allow monero payments or something. Alongside Google play for the sheep that want to use that.
