True, what made me write it was a YouTube channel I came across, they don't accept donations or show ads on their channel and they have crazy views, they say that we don't want to earn money on this, granted that they give it away for free, but it isn't "evil" to get some money out of it, I am not saying rip off students by charging 10000$ per session, but providing something like a PDF version of the online guide for a small amount say $5 would, in the long term, give you some return. That's passive income which you don't have to bother about, like you'd have to bother about ad deployment. We as an industry are funny, we expect everything to be free of cost _and_ the author should not monetize it in any way possible, it isn't evil to monetize that's what I am saying.
