Rick dodges the topic altogether. He spends the whole time talking about "miming" and why it's ok. Everybody in the comments is like "We don't care about miming, what about stealing songs?", to which Rick replied "Oh, go watch Danny's video about that." He makes a very half-hearted criticism about how it's not cool to steal music, but buries it in between rants about miming being ok.
In his closing it felt like he was trying to make excuses for Giacomo, saying that there's a lot of pressure on people to be perfect and that may have been what drove him to it. Then he goes off the rails again talking about how miming isn't that big of a deal.
He very clearly didn't want to talk about it at all, he was pressured by his viewers to say something.
