They aren't posting a positive opinion about it, they just wanted to report that borrowing and lending cryptos are on the rise.  The proof of it is the notice below the article that is saying that they are not advertising it nor giving their positive opinion about it(endorsing) but they are only posting it for informational purposes only. That being said, being listed on the article does not prove that it is not a scam. Still, I think it is too early to judge Ethlend as scam.
