I honestly don't know. It really is very difficult to resist the temptation to misuse power, when a lot of it is concentrated in one's hands.
On the other hand, let's analyse:
- on the "means" side: France certainly has a lot of military power. It does drone-killing of terrorist heads in African Sahel. It launches successful intelligence operations abroad. It also succeeds to counter foreign agents on its own soil (ref the identification in 2018 of a GRU cell in France). It has a very solid cyber-defense.
Also, between strengthening the IT, cyber-army, and intelligence services, and just extraditing journalists after-the-fact (or, imagine, abduct them, drone-kill them, etc), which is most resource-intensive? As an engineer, you know that the part where you develop your own system to be more robust and more capable is harder than just band-aid retaliation around past mistakes.
Guess what, US is doing both, so it's seat-belt and airbag at the same time. Very great, France is doing only seat-belt.
- on the "results" side: France tries (currently) to preserve its image, to appear as "good" (not judging if that's true), by playing by the rules internationally, fighting great causes, etc. Whereas US soft power took a huge tall in its (indirect) handling of Assange case. It is now seen as more "evil" as before. More people, especially a lot of intelligent people, are despising US more.
So, supposing the overflow of power hasn't busted the brains out of the government, they should be weighting means and results, and decide in consequence.
