> A chat is expensive to run
Is it? A mid-size server can support couple of million of users. Storage of large files may cost something but not the chat service is super simple and cheap to run.

Then you got misbehaved scripts, ddos attempts, authentication for every message, encryption...
Yeah, it's expensive as hell, even with an optimised erlang backend.
In fact, if they manage to get all that down to one cent per user per month, which is very cheap for such a service, it's still 10 millions to run just in hosting.
