To be fair… it is not like this is a brand new thing. Traditionally email and other services like hosting and nntp were included with your hosting account. Although webmail and the tv crowd broke those expectations, I think we can expect a similar solution.

I have a mastodon account on a server hosted by a podcast that we all support. I can see a similar solution for all the many other interests and groups we involve ourselves in. Such as local LUGs, or any other number of groups/clubs that already are funded by their members and provide services for them.

At scale, I can’t imagine it will cost much.
