May I ask why you are asking for my email address. My first impression when someone is asking for my email to download something for "free" is that he is a lying piece of cr*p and he just wants to spam me later on.
That's cynical. If someone spent their time making quality things people enjoy, they can charge whatever currency they'd like. If that currency is an email address so that you can be contacted later in hopes of selling you paid products or earning through referrals, then that's their prerogative. It doesn't make them a _lying piece of crap_.
If you use a catchall, create an address for that service. It it does something you don't like, cancel later.
I'm not disagreeing with that but a clean disclosure is missing. It's like paying for an item that you don't know the price of by putting your credit card details. I don't think you'd do that.
An email address is not a credit card. It isn't private information. Do you really think the amount of spam you will receive will change at all if you give one extra person your email address?

You don't know what email address I'm giving you; I generate single-use emails for just about everything I sign up for, so when I start getting spam for it - like I actually did about 20 minutes ago - I can go straight to the source and start asking whether they got hacked, or sold me out.
That's the sleazy part. It looks like you need an email to get a "pdf download link" but if you read the reviews a little down you'll understand that it is just another newsletter but disguised in a "course".
So why give a 20 lines explanation of what you provide instead of correcting the error. This could have been done more cleaner: Have all the free courses available on-site. Have the purchase page available on-site too and from the free courses. Clean. Simple. No BS.
