Illegitimate use:

It's all hype tbh, there are very few .onion sites and they are tiny, most are filled with fake woo foo info like "Leaked FBI Proof of UFO's", "How the Illuminati turned my cat gay" that sort of stuff.

As far as legit .onion sites there are maybe 10 of them they all sell drugs and credit cards.

Legitimate use:

It's used to protect you from anyone that might spy on you, hackers, advertisers, social media, governments whoever the bad actor is.

In the current sate of the internet you make too much money being a bad actor to not be a bad actor. I think there is far more legitimate use of tor than illegitimate use. I would say that tor has more legitimate uses than torrents.
