The context of this thread[1], which you replied to, is specifically the US law. You are wrong on the US law. Wikipedia's general statements about what some countries do is not authoritative or specific to the US.

US law does not generally prohibit insiders from trading. It prohibits doing so only in breach of some obligation to keep that information private[2] ("in breach of a fiduciary duty or other relationship of trust and confidence").

That's not correct. I started this particular sub-thread, and in my original comment I specifically said that the answer is jurisdiction dependent. Your reply may have been US-centric but the overall topic was not.
