They had a net income of 23 Billion Dollars in 2016, so the one-time fine alone is approx. 10% of their net income last year. The daily fine of 5% of daily worldwide revenue would amount to approx. 20% of their daily worldwide net income (using the 90 Billion from Wikipedia as worldwide revenue and 23 Billion as net income).

Since the EU is likely more than just 10%/20% of their income, they still make some money here, but I doubt that it was worth it for Froogle…
