I have a huge respect for both Ellis and Chen, and stated that on several occasions in the blog post. The same goes for what 'growth hackers' do, in fact, I could call myself one since I do both marketing and coding! I just don't like the term growth hacker, as this is just another buzz word for something that just isn't new. I wholeheartedly agree on the ad hominem attacks, they are low. This piece wasn't meant as one, and I apologize if it came across that way.
