Shouldn’t be. Musk was a U.S. SGE and under the material influence of various foreign powers while directly influencing Grok and Twitter. If there is evidence he influenced any of these products against the interests of France in that time, particularly at the behest or in the interest of the U.S. or one of those foreign powers, the charges should stick.
Sure, the point is X would have been operating under unusual foreign influence from Musk qua U.S. official (and influenced by other powers) in France. It’s not clear Musk broke French law. But it shouldn’t be hard to show X did, since there is zero chance they did the sort of siloing enterprises routinely do to protect against such fuckups.
