They did. Google didn't comply.
They are just sour that their precious tech companies are being brought to task for behaving like shitty house guests by not following the rules.
These companies might be able to get away with whatever the hell they please back home but get this; the American Way isn't the only way.
It's just a very shitty dismissal of the very real concerns of US tech companies and their disregard for the laws and regulations in the countries in which they operate. Laws and regulations that EU companies have to follow too.
The only real upset here comes from companies like Google, and their rabid supporters at the prospect of them not being able to implement their shitty consumer-hostile, ring-fencing business model in other countries.
Google were given two year's notice before this fine. TWO YEARS.
It's their own damn fault and the fine is punitive, as it should be.
