If you're going to take such a dogmatic stance in your writing then you should be prepared for the criticism. I don't think anyone is interested in rehashing the debate about the value of ideas on this thread. Suffice it to say there are plenty of very well informed people who have built companies and believe that ideas are valuable and worth protecting. So when you demean your audience by suggesting otherwise you can expect people to take offense, dismiss whatever else you have to say, or both.
