It's over half of Google's estimated annual revenue in France. Not sure how you did that calculation, but if someone confiscated half your income it would not be much like a 62 cent fine.
Google doesn't break out the numbers by country. There are various estimates from 200M to 1000M. Either way this is a hefty fine, especially since France finds a new 9 digit fine to levy every year.
Also does it make sense for you that one region can make fines based on global revenue? Would it be OK if Iceland also gave companies fines based on global revenue rather than the revenue they have in Iceland?
