Rather than giving an entire unsolicited peer review, I would just mention there were issues with the paper and offer a full peer review if he’s interested. It’s clear from the paper that Terence has no idea what the process of a peer review is, so maybe start by educating him on that.
Now, if that happened, or if Terrence sent the paper and asked for a full peer review, I would take back my comment. But based on this video, it didn’t feel like that’s what happened.
