From the text I'm not sure the idea really is to make the author money. If anything, presumably any code others contribute now will be copyleft, meaning if the patches are integrated and re-distributed by the author he can charge for distribution - but have to distribute under copyleft. I also wonder how many corporations integrate and redistribute nodemailer; I'm sure there's a few - but I'm guessing most just use nodemailer. Apart from paranoid legal teams, the licence change shouldn't make any difference. Now, someone distributing a firewall appliance using nodemailer for sending email alerts would have to provide customers with a copy of nodemailer source under copyleft - along with any changes. I still don't see why that would translate to payments to the author.
