The NYT article doesn't even mention organized crime, just French delivery workers subcontracting out their deliveries. It is sort of an ironic twist on the independent contractor vs. employee debate:
> French labor law allows independent contractors to outsource to legal workers, but Uber Eats, Stuart and Glovo said they prohibited subcontracting.
Sorry, can't find anything about how organized crime has taken the field.
But: if this happens in Marseille/Nice, I'm ready to bet organized crime has a hand in it. Mafias still have a lot of power there, and they're taking all the fringe paralegals businesses.
