That's true, but as one of the links mentions oil is used in large quantity and is the top contributor even though its ratio is fairly better than other items.

So if you use butter or coconut oil, you're getting around 400 vs 2.6k omega-6. So if you eat something that has better omega-3 ratio you'd need to eat lots of that to balance it out. When you switch to butter from canola you are essentially trading omega-6 for monosaturated/saturated fat.
