Upvoted, because what you said was strictly true and possibly insightful. (Is it still insightful whether the person who coined it actually had the insight that the statement implies?) I'm not really sure what you meant to imply, however, so I hesitated before upvoting.
Actually, I think it would have been more insightful for me to say interpretation isn't free. Dissemination matters, but the interpretation is primary.
Information is inherently free because information is basically numerical, and anyone can (potentially) think of any number. However, information is only useful when the numbers are correlated with actions or objects. It's this correlation that is truly valuable, and the creation of the correlation requires resources (i.e. time and energy).
Probably more information than you needed.
