> In the two most recent forks developers first lost access to the original tree
The sequence isn't the important part of what I was getting at. That said, have there been any cases of Linux developers who have been blacklisted to the point where their patches are refused out of hand?
> And at least in the case of FreeBSD and DragonFly, plenty of developers worked (and still work) on both projects.
After I re-read what I posted I knew someone would call me out on this. What I mean is that after the fork the two things are thought of as separate and worked in separately, which is very different from the thinking of Linux forks, even ones which are large and have existed for many years. There's still the common tree.
