Agreed its a stretch, my experience comes from Google when I worked there and they set up a Chinese office and they were very carefully trying to avoid anything on premises that could searched/exploited. It was a huge effort, one that wasn't done for the European and UK offices where the government was not an APT. So did X have the level of hygiene in France? Were there IT guys in the same vein as the folks that Elon recruited into DOGE? Was everyone in the office "loyal"?[1] I doubt X was paranoid "enough" in France not to have some leakage.

[1] This was also something Google did which was change access rights for people in the China office that were not 'vetted' (for some definition of vetted) feeling like they could be an exfiltration risk. Imagine a DGSE agent under cover as an X employee who carefully puts a bunch of stuff on a server in the office (doesn't trigger IT controls) and then lets the prosecutors know its ready and they serve the warrant.
