I think you're being a bit uncharitable with the intentions of the author.

From the author in the comment section of the blog post from your first link:

'I’m showing this email here on my blog as an insight into what it is to be Daniel, author of curl. I don’t understand how you can make this into “making a profit of”, since this is just an email someone sent me and I’m not revealing any details to allow anyone to identify who this person is.'

The only insight I can draw from this is that “Daniel, author of curl” has to sometimes ignore unwanted emails?
