I am planning on selling software which is licensed under GPL 3. I have gone through the terms and conditions listed in the GPL 3 license. However, I would like to know if any of the following scenarios will violate the GPL 3 license:Can I charge the customer for software? This includes selling thesoftware as well as charging for technical support? If the software is known by name 'ABC', can I change the name of software to 'xyz'.This may include changing the logo, name on the UI?Do I need to provide the copy of source code voluntarily? I am fine to provide the source code if some body asks for it.Is it necessary to publish the modified source code if I host it in the cloud?
