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.

Not to be that guy, but there's a significant difference between Finland versus Netherlands, Germany, and even Ireland in importance within the EU and European institutions from a power politics perspective, as well as the type of political culture.

Pre-1995 EU member states tend to have stronger control within EU institutions, and are the states that actually matter along with a couple later EU member states that have openly threatened or actively reversed into illiberal democracies that tried to stymie EU institutions and/or created their own groups to pressure the EU such as the Visegrad Group.

From a US perspective, as long as Russia threatens Finland, Finland has no choice to look to the US, especially if green men suddenly appear on Etelakari, Kilpisaari, or some other rocky island in the Gulf of Finland, especially now that pro-Putin Rumen Radev has won a majority in Bulgaria, Babis and his coalition have returned to power in Czechia, and Fico in Slovakia remains in (tenuous) power.
