I thought about monetisation and it’s also in the talk linked but ultimately I’ve decided to not monetise it. Instead, to make it sustainable, I’ve created a separate app called Aether Pro at https://aether.app. It’s a much better version of Google Groups. You would use it if you wanted the modern features of Slack like channels, guests and integrations, but you also want to keep email discussions as your main work tool, and not move to chat.

By having them separate, I can make sure that the the P2P version isn’t influenced by money-making concerns, since we have a product explicitly made for that.
