I'm happy that the environment allows people to develop alternative ideas in whatever way they see fit and are able. I support innovation in the form of truly new ideas, but also if existing ideas are reimplemented in a different way.
Me, too. Even the re-implementation idea is good.
Re-implementing a library is acceptable because libraries can be exchanged for another easily by almost everybody.
In case of a network, it is not re-implementing. It is re-creating a complete new ecosystem using its own resources. One does not simply substitute each Nxt node by a Qora node AND having the complete user base transferred.
