Facebook ARPU for Europe is $19.04 per quarter, or $6.33 per month. This is based on monthly active users and includes Messenger. If you adjust for that - someone paying for a subscription is likely to be much more active than an average monthly user - it's likely that 10 EUR is a loss. The big winners are Apple and Google getting their cut if it's an IAP.
The economics are even worse in US/Canada, where an MAU is worth $56.11 per quarter, or $18.70 per month.
