Very valid point, whilst some evils are necessary, I think it might be responsible of the author to point out the greater context of what he is doing and why so people don't start doing this willy-nilly. As a contrived example, an article about "How I replaced my engine using a crowbar" might lead people to believe that is the ideal way to replace engines and have mechanics groaning everywhere. If however the article was "How I replaced my engine using a crowbar whilst stuck in the desert with no other tools to hand" then everyone would understand a) don't do this in normal circumstance, b) there is another way to do it in less normal circumstances.
