They should be ordered to pay 45% of the company. Hand over the shares. If shareholders lose ownership, then they'll start to pay attention to how the company is run.
And the penalty for non-compliance, another 0.5% fine?
So long as repercussions aren’t more serious (see EU fines) or more personal (hold C-suite personally responsible for contempt of court or similar), nothing will change.
Threatening to nationalize, restructure, and then sell the company for cheap to someone that agrees to operate it within the bounds of the law… that might have some serious teeth.
They think charging business 30% of their revenue is completely acceptable, so a fine must be something above that number.
Any fine on revenue below 30% is just a cost of doing business.
