That's basic proportionality.
That is entirely tautological. It omits the reasoning under which that spectacular amount of irreparable damages have actually occurred to consumers.
"They have a lot of money and we would like to have that" is not a valid method of calculating damages.
the fine has been calculated on the basis of the value of Google's revenue from search advertising services on Android devices in the EEA.
In other words, Google had an unfair advantage for search on android devices and leveraged that into revenue. The fine is a percentage of that ill-gotten revenue.
There’s an official guideline for calculating damages when anticompetitive behavior is found: https://eur-lex.europa.eu/legal-content/EN/ALL/?uri=CELEX:52...
