You keep saying this, when it is counter to the actual text of the article.

> Yet aside from the raw corruption, these incidents also raise a larger question....What broader damage does this kind of unchecked insider trading do?

That is what the article is about. It's saying that this is corruption, and discussing what the effect of this corruption is. "Beyond just corruption" is wholly your invention. I don't even know what it would mean?

Corruption is the cause. The article discusses the resulting effect.
