When was this published? I see the approval for release date, but not the author's publish date.
Relevant lines:
"Representatives from the Organization for Economic Cooperation (OECD) backed the concept of key recovery systems during a January 1997 conference."
"The software industry estimated that, if export controls were removed, US companies could sell as much as $60 billion a year in encryption hardware and software by 2000."
He writes that in the context of describing the business leaders' arguments at the time. He could have written it much later. For example, I could write the following today: "Ronald Reagan estimated that unemployment would drop 2% by 1988".
That said, I see no definite references in the article past 1997.
