Because from personal experience they don't care. The best of the best policy wise immigrate to the US to take a think tank position in NYC, DC, or Boston earning 3-5x what they could in Europe, and the rest become lobbyists in Bruxelles. After making their nut, they then return to politics with a funding pipeline because campaigns are expensive (even in Europe).

The ones who feel deeply about the cause don't know how to execute but only pontificate (dealt with plenty of EU AI policymakers with European AI founders).

Heck, even consulate employees who are part of the trade promotion teams for most EU states try to network their way out of the role into VC jobs in NYC and SF.

You are generalizing too much. Europe is full of different electoral systems, and each system has its own dynamics that favor different kinds of people.

Take Finland, for example, with open list proportional elections. The primary competitors of every candidate are other candidates from the same party and district. In order to win, you have to develop and maintain your own niche. Many politicians leave to become lobbyists or consultants or join a think tank, but it's almost always a one-way street. It's difficult to return to politics after an extended absence, because someone else has already taken your niche (if it's still viable), and money and experience rarely help win it back.

As for the actual question, many European countries seem to consider trade secrets primarily a contractual matter. Revealing private secrets is not a crime, while abusing your position or breaking into a system without proper authorization can be. Prosecutors generally cannot invoke national security without a clear legal basis. Which probably can't be found in matters that are more about Western competitiveness in general than about the security and interests of a specific country.
