Thanks for summary! The claims give me a really strange feeling that culprit tries to attack in defence and tries to become victimized. In regards with the claims, 1. Or do they? Or may be they do in certain cases? How can you guarantee that if the output matched your biased assumption but the output is non-deterministic that it's actually proves the theory? 2. That's may be an excuse to some degree 3. Bad excuse, it's all varies by design of the app. You can write either easy to test and modify code or spaghetti-code. Even if the code very volatile investing in proper design of the app will give you a plenty of room for unit testing 4. May be there are some of them who actually do have a grounding. In the age of internet it's quite easy to learn the basics having some math background. It won't make you an expert in that field but will give you enough to spot obvious mistakes. 5. If they personally can't do that why not to gather community together and combine the effort? Especially when it's a deadly epidemic. 6. Or may be somebody takes the critics too personal. Take it easy, you can always void it by a phrase - "please send a Pull Request". But you need to be ready to collaborate and actually accept PRs. The whole situation looks very dirty and it's hard to filter out personal attacs and false critics. Although there are definitely some valid ones. edit: formatting
