One difference between politicians & lawyers when compared with scientists & engineers is that politicians & lawyers don't share the same feeling of needing to precisely define what they mean. They tend to write things that are vague and turn to courts when they desire enforcement.

You might be let down if expecting something so specific that Amazon & TechCrunch are clearly included or excluded.

This is certainly true in places with legal systems evolved from that of England. It's less true in France, where precedent is less important and courts don't have the power to make law.

Interesting; I had no idea that difference existed. Thank you for correcting me.

"Common law" is the name for a system that is mostly built on consistency with prior judgments; "civil law" mostly built on legislation.
