Mostly employee is main expense. employee, server fees, travel gets up to like 100k/year probably more

Ok so scaling is massively important in order to make paid relay subscription rational for a user. Explains why some have dramatically increased cost. Shocked me and stopped on one.

Complicated when competing in an environment where centralized systems monetise through data collection. Tough nut
