Offer the information for free...AND a book, that's fine.
but you don't get to say "my time is valuable" when you are simply parroting information. That has no value, and is ethically bankrupt. They pay money for something with no value. He doesn't MAKE anything, or DO anything of value.
"I'll give you the answer if you give me money" is ethically indefensible. It's accurate information (mostly) but has NO answers. If it did, why would he be here?
