You misunderstood the GPs statement. What they meant was [the reason this is a problem is not because] it's a small fraction "extrapolated over the whole fossil fuel industry" Not [There is no problem because] it's a small fraction "extrapolated over the whole fossil fuel industry" The words the commenter used: "This isn't a problem because" can mean either in English. In other words, they were saying the article was misleading because TFA claims that the problem is due to a small fraction multiplied by a large industry, while it's actually a very large multiplier multiplied by a large industry.
