That's not true at all, back when they were good they brought insightful commentary and criticism to games people actually knew and cared about. Look at the old episodes and the games they list.
For example, on Episode 24 they talked about:
Rhythm Heaven,
Henry Hatsworth in the Puzzling Adventure,
Brütal Legend,
Dragon Age,
Bully,
Tap Tap Revenge,
Shadow of the Colossus.
Look at those games, look at that shit people care about. And when you look at the other old episodes, same menagerie of shit worth talking about. And it was great! Back then, I totally wanted to hear what they had to say about Dragon Age because chances are it was going to be a bit deeper or a little more different than what someone at IGN would say.
Here's the list of games on their latest episode:
Nuclear Throne,
Flywrench,
DayZ
Ugh.
