What would it cost to run the #fediverse at scale? With billions instead of millions of users?

What does it cost to run a social network anyway? According to the annual reports of two companies that should know, the comparable seems to be about $1-$2 per user per month. And that's after stripping out a bunch of costs, like us not building ad tech in the fediverse.

Have better numbers? I'd love to see them!

@j12t @leobard This one euro is not based on a precise calculation, but on the assumption that an instance should not have more than 50,000 participants and that the operators (including marketing and cleaning staff) must be able to make a living for themselves and their families. We are still working on, or rather thinking about, the refinements.
