Re: A little off topic…
That would be a point if:
Java was made open source in 2005, as part of publishing solaris soruce code, before being made closed source when Oracle acquired Sun in 2009, then forked as part of OpenSolaris, to continue its development as an open source project, including ongoing development of/away from the original code base.
ZFS is desirable in Linux for reasons of technical merit, but as closed source, that's physically impossible.
I haven't seen any credible legal opinion on the risk of putting OpenZFS into the Kernel ( and to assist those googling a link to the Linus diatribe, that's not a legal opinoin - it's a management risk position statement, and he does not address OpenZFS ).
