Hm, You seem to be right!

I just spent the last several minutes reading reputable sources and they all seem to agree with you. In fact, they indicate a pound of muscle burns more like 6 calories.

You win, Internet.

This article misses a key point: increased muscle mass correlates with increased calorie burn.

Not all exercise is created equal. Exercise that doesn't build muscle is indeed ineffective at burning fat. But exercise that DOES build muscle has a compounding effect on burning fat. Your muscles require more energy to maintain, so they will burn more calories just by existing.
