I think they are either refering to child labor in cobalt mines, which was used for Tesla power elements, or to his father’s emerald mines. There’s no evidence of direct people-owning slavery in either case, still a lot of shady and immoral (and probably illegal) practices to earn money in both of them.

Still better than what’s going on here in Ukraine, when you question whether it’s someone riding a motorcycle or it’s an attack drone coming your way😅

What did YouTube do tho?
