I said mostly the same thing as you in (my own words) elsewhere inside this post. Most people don't want to see this reality.

So, maybe this is a business opportunity : to attract investment and then face investors with hard facts. Of course we write the contract so that, after this, we just keep their stupid money.

Edit : Oops ! I just read your other comment :

you’ll also see (...) investment scams

And so I realize you were thinking along these lines already. (although my statement was much more cynical)
