That’s the problem we face from time to time. We sell radio streaming servers and people use various broadcasting software with our servers. Some of those software pieces are free, with no customer support. Customers contact us with questions like “can you try app <…> and see what could be wrong there?”. Sometimes they directly say that “I’m using free app and they don’t give me any support, can you help?”. As I don’t intend supporting someone else’s free software (we’re business, not charity), we politely refuse, and offer using our paid software instead.
Does anyone face the same customer support issue? How do you deal with it?
