Is the developer paid to be friendly to users? If not they likely wont be, dealing with users isn't fun, especially as most of their complaints lies out of your control. So developers working for big companies or developers working on free open source projects likely wont be very friendly. Developers who work on a project they try to sell will likely be friendlier though, at least until the project becomes so successful that they no longer need your money or they realize that you don't intend to pay for the fix.
