It's literally other people's content copy-pasted in a "book". Even "free" (you still need to enter an e-mail address) that's not a great way of generating content (I guess you could argue there is some marginal value in selecting 50 "good" posts?), taking money for it is pretty slime-y.

I would agree with you if it were not possible to pay $0. But, there was work that went into compiling and laying this out, and that does add some value. I see no problem with offering this content on this basis, for the price of an email address, especially considering you can use a throwaway address.

Then don't buy or exchange your email for it? I'm not sure why you feel the need to tell the rest of us how to morally evaluate this optional e-book. I traded my email for it and my morals weren't violated in the slightest.

Are you planning on competing with the product or do you just want to see that person fail for no particular reason?

I just gave an answer to a question asked.

“The only thing necessary for the triumph of evil is for good men to do nothing.”

I mean I’m not a good man so the quote kind of falls apart but you get the idea.

There is no fair price for selling the work of others that you don’t have the rights to take.

And you know they don’t have those rights?

Wouldn’t they have made it clear if they did? Isn’t that traditionally how using someone’s work under a license works?

Did you ask them?
