Well, looking at the following things sort of gives it away:

- brtfs vs zfs

- cgroups vs jails

- SystemTap vs dtrace

- Systemd vs smf

I get it, many of these were due to licensing issues. So they said[1]. Anyways, there are still some things to implement for linux. pf is my favourite (software) firewall. It would be great to see it ported to Linux.

In my experience, both Linux developers and BSD developers don't seem to care too much about porting things to the other's operating system. If you want to do things the Linux way you can use Linux, and if you want to do things the BSD way you can use BSD. That's seen as easier than trying to glue two incompatible things together.

BSD developers can't port things from Linux in a straightforward manner due to license issues. But that doesn't apply the other way around.

Won't, not can't. *BSDs shipped GPL components for decades before they decided to go for purity. It's a policy decision, not a incapability or mandate.

I don't see why. BSD and GPL are equally compatible, it doesn't matter which way you go. I can see why they wouldn't want a GPL component to be mandatory but it can be made an optional component for Linux compatibility which seems to be the way BSD would want it anyway.
