(Assuming we’re talking about US law) Since the previous comment was talking about commercial use, there’s no entitlement to use someone else’s code for commercial purposes at all absent some sort of license agreement (or waiver, or fair use, or some other exception). If the license granting the right to use the code in the first place requires sharing changes, then someone using the code with modifications has to either share the changes or infringe copyright.

Standard dual license commercial and AGPL that most companies use. These are copyright licenses, Once you allow me to download the software, I can do anything I want to it but distribute. Licesense only invokes on the copy hence a copyright license. Copyright licenses can only grant rights not take them away, so they can't control how I use it privately.

  Copyright law is concerned with the making of copies, not just with their distribution. Fair use covers making personal modifications to software for personal use, but does not cover modifications for commercial use.
