The requester is wrong. You are the project leader. You are the decider when it comes to the project. Do you think this makes your project better? If so, cool.

The requester is wrong. You are the project leader. You are the decider when it comes to the project. Do you think this makes your project better? If so, cool. If not, say so. If someone is badgering you, then feel free to charge them money for your time. They can choose to sponsor the development of a feature that can be used by everybody. Or they can choose to pay you for custom development that they would own after the transaction. One thing that I do (in the US) is I have very specific guidelines about the transfer of copyright and licensing. I own the copyright to the code, full stop. I don’t offer copyright for purchase. What I do offer is a long-term, royalty-free license to use that copyrighted software that I give them once payment is made in full. If they use my code or my designs without a license, then I have the ability to file a copyright infringement case. Thanks to the Recording Industry of America (RIAA), copyright infringement cases can be upwards of $150,000 USD per infringed copy, which can be translated into a download, which can be translated into a website visitor. Very quickly, companies realize that it’s in their best interests to pay what they owe me. Having said all of that, if you don’t want to do it, then just don’t do it. But you have to have the backbone to say no. Set boundaries for yourself, and then enforce them. But backbone is what makes the world go round.
