I have been kind of wondering about that investigation. If their HR is already 3rd party, continuing to use them would technically be a 3rd party investigation. Linus said their HR team is investigating, and they're hiring someone outside to investigate, are they hiring two HR firms? I looked at LMG's staff page, and they don't have any HR listed there. Only a Talent & Culture manager and coordinator. Maybe that's HR? Seems doubtful.
I just feel like they might be calling in the same 3rd party HR firm that they've been using, find no evidence, and keep on trucking.
