> Do you have any idea how expensive it is to keep the infrastructure running?

Yes, I do. All hardware and bandwidth are donated by Fastly and AWS so it costs RC nothing. Their expenses were $20,000/mo for 24/7 ops coverage: $2000/mo for 6 people and $8000/mo for service maintenance (e.g. db and software upgrades). So $240,000/yr, not "millions".
