"Echo chamber" is meaningless nonsense at this point. That's just a phrase people throw out to indicate displeasure with any conversation that doesn't cater to their particular biases. It's basically become another "thought terminating cliche"[1].

Not really, or rather, it depends on who's calling what an echo chamber. If someone's using it to shut down discussion, then yeah sure. But if you can't recognize when you're in one, then you're the one losing out. This is especially important when interacting with sales people, who benefit greatly from customers who won't or can't or don't look critically at their product offerings, and if their prices are at all reasonable.
