No offense meant, but maybe you need to realize that not everyone shares your opinion. What you deem "melodramatic" is, to some artists (like for example the doujinshika who closed down her site because she got a bunch of asses making fun of her -- saying shit like "I hope we make you cry" -- when she politely emailed someone who had scanned and put her books online), the only way they can protect their work.

Everyone has different opinions, and just because you'd be okay with someone taking credit for your hard work doesn't mean others will. I really don't see why respecting other people's wishes has become this idea that is nowadays worthy of mockery and/or just plain lack of understanding.
