In FOSS, user feedback is the worst. Somehow there are a lot of people who think that since they did us a favour and are using free and open source app we developed, they can boss us around and tell us what to do, and give us stern talks if we don't fix the bug they are experiencing on time. "Is that how you serve your customers?" - some say, despite never having paid a single cent. - "you are too immature to run a business" If the app is on Google play or Appstore, it gets even worse: the users there can rate your app from 1 to 5, and on this basis demand premium service. Sigh.
