    Do u think promoting such tools is good (for business) ?

      I didn’t got your context properly but as far as i understand you are asking about viewing the code that is proprietary or not allowed to be viewed by developers such as third party proprietary APIs etc. Yes it might not be good to view some ones code if she doesn’t allows. But these type of tools are not meant for such purposes rather they are to assist developers to view (legally) any undocumented classes to understand their functionality. The businesses concerned about hiding their code can do much other things to prevent exposition to such tools:)
