This. Although I agree with his view for free software, the way he convey his messages smells too much of fanaticism for me to swallow.
If he can't communicate his ideas in a calm and balanced way, perhaps those ideas don't have as much value as he thinks they do. Sorry, but method of delivery counts for a lot.
Whether or not I agree with it I found it quite calm and balanced (just like the phrase quoted above). Note there are no insults or exclamation points.
Perhaps his writing isn't the issue here, but your perception.
