A metric I like to use with these kind of nostalgia-laden stories is how often the word 'free' appears, even in parenthesis. To save you some time, the answer is 14 times. And each of those 14 occurrences is exclusively as a prefix to 'BSD'. Complaints around how Eric failed to understand the the key element of free software, because he eschewed the word free, and when the subsequent reviewers missed this, should be easy to algorithmically flag.
