Basically yes but in fairness there is a bit of operational expenditure. You need to pay a bit for energy (there is still a computer that needs to run), internet costs and your HW may need to be renewed every 5 years or so (perhaps longer). Typical costs of a normal consumer grade computer plugged to the internet, almost insignificant but not strictly zero.
