body: Most news sites and tech blogs provide only a summary in their rss feeds. If I write a script that scrapes their website and extracts some useful data, can I share the script as open source. Does it depend on each and every website and needs prior permission? If scraping is not allowed without permission, who is guilty, the person who wrote the script or the one who used them? 
  
  
  Note 1: I am not redistributing website's content, just sharing the script that helps to read the content in different form. I am specifically interested in Indian and US Law.
  
  
  Note 2: The script may be specific to particular website and may access data that is accessible only with user's login credentials.
  
  
  Note 3: script means a program or software application
  
  
  E.g nytimes offer subscription offer at $3.5 a week for web+smartphone access. But for tablet access, it is $5.00 a week. Can I sell an app for tablet that parses the page from the web interface and converts it to tablet friendly format. The app will use login credentials from the user to login using a virtual browser to download the content and format it such that it is better readable in tablet? Do I have to get permission from nytimes to sell the app? I don't care about this special case but in general can the provider legally restrict how the content is consumed by the end user.
