No they arent loaning it out (as far as I know).
What they did here is they had STEEM on their exchange, where they are the custodians of it, powered it up, and then voted for Tron's witnesses. Thus, they took tokens that were not theirs, locked them up for 13 weeks, and got involved in governance of the blockchain.

Oh, they transferred people's money from their exchange (where it was agreed to be stored) to private Steem blockchain accounts? That's close to theft.
