Open Source is not about having source code. It is about the license meeting OSI's requirements, which are more or less the same as GNU's four freedoms. The main problem with Minecraft is how Microsoft, due to Mojang's decision to sell, is at the centre. This is such an important game to computer history, and it has such huge community. It deserves better than this. IMHO the community is best served by alternative, actual open-source clients and servers, and it would be healthy to recreate everything Microsoft currently owns. Minetest is one such effort. This one is from scratch. The incremental approach is another possible route.
