I agree that it is unfair to limit the selling of the materials once you are done with them, but unfortunately when you purchase them you enter into that agreement with him.
IANAL, thankfully, but I smirk at the validity of that "agreement" which he conveniently prechecks on the web page where one enters a credit card number to order a physical item. The fact that he gave some legal prostitute a few dollars to type up a legal opinion carries little weight with me. Scratch that; the
only weight it carries is to stir my disgust.
This is essentially an end-user license agreement, aka shrink-wrap agreement, like the ones software companies have been trying to foist off on customers for years. And although shrink-wrap "agreements" such as Jensen's are extremely common, they've been held invalid by most courts that have examined the issue, exceptions being the 7th and 8th circuit courts (says Wikipedia).
I just think it's a travesty that Americans are voluntarily surrendering their property rights because some dude has a web page that makes outlandish legal claims and threats.
Anyway, I have every intention of buying both Big Blue & Audio Blue from Jensen ... albeit in a year or so, 'round about the end of my CA-2 year. He produces an excellent product, and although I think he has his head in his ass about this particular issue, I can't say I'm upset enough about that to not buy his review materials.
