Actually the lesson is a little different. This is about the dispute within government (courts are government too).
One part of government wanted to side with larger, more powerful and wealthier corporations, the other took side of the smaller weaker player.
The market has to be regulated in PROPER way, in a way that the wealth does not concentrate too much (that is why we have anti-trust laws) and that weaker or poorer players are supported (this includes individual workers/trade unions and small businesses).
Once the concentration of wealth passes certain threshold, the strongest will acquire such leverage that market will stop to be free and average citizens will be disfranchised. See my tagline.
The difficulty is in finding what is the proper balance. Unfortunately we cannot have an easy ideological formula like the one used by Free Market Fundamentalists or Socialist. Real world is complex and we are doomed to improvise and to struggle with contradictions.
