It is worth separating this discussion on user space and kernel space
lines. The kernel space RDMA stack is where the GPL infiltrated and
became a problem. User space is still quite happy with a reasonable
license that promotes use in a broad range of scenarios. This is aided
by the fact that APIs are often implemented as libraries and people
commonly are OK with libraries being somewhat permissive in their
license as they are intended to be used by more than just open source

Yes. Jason and I have both argued this many times. If the software is
forkable, then you don't have "control", except by the acquiescence of
your users. When that's the case, it is the quality of your stewardship
that matters, and what keeps people from taking the nuclear option of
forking and going their own way. Once the OFA got the RDMA subsystem
integrated into the Linux kernel, it was inevitable that there would
eventually be a licensing issue.
