This reads like a blithe, poorly-written high-school essay on the problem with "view source": With the advent of HTML5, the web apps become popular, especially the mobile web apps. Web apps can be classified as either Hosted App or Packaged App. The source code of Packaged Apps (such as the apps in Firefox OS or Tizen OS) are installed and running locally. Users can easily view the source code. Similarly front end source code of Hosted App can also be easily seen by anyone. In this case, the publicity of source codes becomes a problem. Because web developers never hope their web apps are easily copied by others.
