From the article:

$100,000 per day for a country with ~5.4 million people is a lot. If even 20 percent used Facebook regularly, then that would still be 10 cents per user per day. It's unlikely that Meta is generating so much profit per user - every day.

This is a reasonable observation and I wonder what Meta would do once one of their services becomes unprofitable in a specific country. Anyway if you add Instagram and WhatsApp to the math, maybe they would still generate profits from the Norwegian userbase
