The fine is arbitrarily decided. There isnt anything solid governing the amount if the fine is not % of revenue. So it totally depends on the whim of the regulator. Which is totally in lieu of the principles of civil law that Europe uses. Its more like the common law practice in which the authority can interpret things and can act arbitrarily without solid, inviolable, democratically-made laws governing its behavior.
This may look like working today. Tomorrow you may find it disproportionately hitting whichever segment or sector that the interests behind the incumbent regulatory appointees target.
