except we are speaking about lying under oath, not espionage, you don't get a trail for espionage because you lie under oath

and leading management also technically doesn't need to know that is happens for it to be doable. Or in other words they have a lot of reason to "accidentally" not know about it/have it overlooked

this means even if it happens they are very unlikely to be charged for anything more then negligence

but the contracts I mentioned above basically state "it doesn't matter why it happens and if you knew or if it was your fault as long as there was the smallest bit of negligence on your side you are on the hook for it personally". So in a situation where they can effectively avoid espionage trials (because they didn't commit espionage, just negligence) they still are hold responsible

if high level management would reliable go to prison for things like that you wouldn't need additional contracts to make sure they actually have insensitive to actively try to find/prevent anything like this/act very non-negligent.

He wouldn't even be charged for lying under oath if he lied and it became apparent, because there'd be not considering the much more serious espionage charges. They'd only prosecute the espionage part.

Participating in a plot to supply french state information to the US is espionage. France also apparently has a broad definition of espionage, relative to some other EU countries.

States have a tendency of coming down rather harshly on this kind of thing, so this idea about negligence is I think unlikely. If you know about it the charges will be espionage charges. If it happened it would be the biggest thing ever. They'd arrest most Microsoft employees in relevant teams as well the leadership, probably many others too. Just interrogation would probably take half a year due to lack of interrogators.
