I read a lot of articles and information regarding my questions, but those answers were very technical and I wanted to understand the law in simple English.

As per above Link, I can commercially use the software.



I have modified in GNPL GNU Application and selling it to my customer for a fee via a Web Portal.
I will include a Copyright and also License copy of original software which I used. Is the enough?
My Problem is disclosing the upgraded code, I am ok sharing with people when they justify me a reason to get free access to upgraded code over an email, but I do not want to simply publish the code over the web or URL for the world to see, because check below



Imagine two situations which support my above line.



1)My competitors can copy the same code and resell, then my investment for customization goes into the drain. 2)As per TDRLegal, I can even claim a patent for the upgraded product going future or I can we are inspired for X Open Source Software and charge for the upgrade as one time free.



This is a situation which most of the small startups have faced and wanted to know if there is a workaround the law, where we can use the open-source at the same time stay compliant with the legal law and protect our investment made over time by customizing the open-source software.



Please suggest the best actions.

          You aren't required to make code public - but you are required to make code and all changes available to anyone that you distribute binaries, etc. to. So supplying source on request of only the people/groups that you have licensed your program to is OK and permissible.



          Not sure on GPL3, but for GPL2 it is even permissible to have the recipient make a request for code, and then you mail them the code on floppy/cd/backup tape/etc - electronic format is required, but electronic delivery is not.



          Be aware that anyone who does obtain a copy of your code after requesting it has the right to put a copy out on github, etc. Hence the "free" (as in money) nature of many pieces of Free (as in liberty) software - redistribution at no cost, etc. is almost inevitable.

            The GPLv3 only allows the written-offer mechanism if your distribution is embodied in a "physical product" (per 6b) or else "occasionally and noncommercially" (per 6c).
