What is espionage? "The act of obtaining, delivering, transmitting, communicating, or receiving information about the national defense with an intent, or reason to believe, that the information may be used to the injury of..."

And, what's a journalist? Someone who publishes information/analysis. Some focus more on information-gathering, and then publish their discoveries. Others focus more on promoting a specific narrative, leaving information-gathering as a secondary concern. But a journalist who happens to obtain or publish information against their nation's interest is not automatically a spy.

You may choose to count saboteurs and assassins as spies, contrary to the dictionary definition, but consistent with popular usage. If you do, these represent a vanishingly small proportion of the overall number of spies, and are not germane to most discussions of espionage laws (laws against murder, theft, destruction of property, etc are not particularly controversial.)

For the most part, spies gather information and publish to a small audience. They are, essentially, doing journalism for a specific group and refraining from broader publication of their work.

The second most common espionage activity is propaganda - essentially journalism with a bias that is paid for by a foreign power. The audience may again be limited, as in spies dedicated to propagandizing only specific useful targets. But the goal is the transmission of information (false or true) rather than the gathering of information.

What distinguishes espionage from ordinary journalism is that the spy is paid by (or has her loyalty otherwise secured by) a power (nation, corporation, or other conspiracy) that we regard as hostile, and is willing to violate journalistic ethics in support of that employer. Simply limiting the scope of publication does not make one a spy; nor do violations of journalistic ethics; nor does targeted propaganda. It is the motivation that makes one a spy.
