It is not only that but he does not like to organize code in a good way and does not care about security too much either. Pax team was asking him to merge in the security patches to mitigate some of the problems inherited from the monolithic design and the lack of kernel and user space memory separation but those efforts were greatly ignored. On the top of these he is suffering from not-invented here attitude (to be fair this is common in the open source community) and license problems as well. This is why everything gets re-implemented in Linux, prime example is dtrace vs. opentap. I think the world deserves a better kernel that is designed for the modern era, security and maintainability kept in mind. There are some interesting work done in few projects already: https://github.com/cloudius-systems/osv https://github.com/cloudius-systems/osv https://os.inf.tu-dresden.de/L4/ https://os.inf.tu-dresden.de/L4/
