Yes, I agreed with the entire article as well. I didn't see anything controversial or exaggerated about it.

Edit: Ok, maybe I could have predicted that lines like "HTML 5 is a plague on our industry" would ruffle some feathers. I guess I like a little snark in my criticism.

This kind of well thought out constructive criticism leads to interesting discussion and eventually improvements, even if I don't necessarily agree with it - hence the upvotes. Dissent should be welcomed, especially when it's in a well-meaning tone.
