I don't like podcast beyond or IGN at all really, but you are a bit off base with your issues. First of all, the guy who didn't know what PS TV is was a guest on the podcast this week, and he covers Xbox stuff on IGN, so he has no real reason or obligation to know what it is. Also, Colin is weird, and absolutely hates any interaction with people in gaming, be it co-op or PvP, so he would never do Destiny PvP even if he got to max level (he is a weird guy). But for those reasons, he made sure not to be involved with Destiny reviews or site content, because he knew it wasn't for him. I don't think he shouldn't be able to talk about his opinions on his casual Destiny playthrough though.
I think podcast beyond is pretty bad and I disagree with most of their opinions, but I don't think there is anything wrong with someone talking about his experiences with a game after a few hours. Not like he was trying to hide how long he played and pretend like he had extensive knowledge.
