I wrote the blog post. I suppose you guys are right - poor choice of terminology. I read Kane's post - which was mostly about why he isn't going to release his software for free anymore. I started thinking about the business reasons why i release software for free (which i do sometimes, but not always) and it occurred to me that i use it as a tool to allow me to more quickly test out an idea. That was really the main point i was trying to make. I will try and update the post tonight to make the language more consistent with the point i was actually making (focusing on testing hypotheses to mitigate risks as a startup and using a freely available product to help test those).
