Red Hat vs. Ubuntu: Why upstream commits matter
There has been some 'debate' that has bubbled to the surface again recently about Ubuntu vs. Red Hat on the issue of who contributes what to Linux.
Red Hat leads the Linux world with its contributions to the core Linux kernel and it also leads with its contributions to the GNOME desktop project as well. Ubuntu on the hand does contribute (not as much), and is focused on 'fit and finish' for the most part.
I personally don't have much issue with the fact that Ubuntu doesn't contribute as much upstream as Red Hat -- though it is something that matters. Let me explain.
If you need something fixed or done, then you make that contribution upstream. Doing everything upstream is the only way that Linux will remain un-fragmented. Without upstream there is no Linux community.
