1. Open source worked as expected. Some MIT-licensed code was forked under the same licence, giving users more options and contributing further to the open-source codebase.
2. I don’t understand the claim about users being confused between Spegel and Peerd. These are two products with different names and maintainers. Maybe some users are also confused between Ubuntu and Red Hat Linux - so what? I’m glad users have more choices.
3. The point about the original author not being given enough credit is the only valid one. The legal side, discussed in other comments, seems to suggest they’re within their rights, but they could have done better.
