Linus's only point was that ZFS for Oracle reasons can't be included in the kernel (despite what Canonical thinks). ZFS may have some nice features but is not worth the headache to rely on a possible copyright infringing, out-of-tree model backed by Oracle.
I have thus far seen nobody who disagrees with this. Instead people seem to got hung upon nitpicking or their own ego. E.g. but the features are important to me and not buzzwords. Good for you, every non-BSD OS thus far lived without them. Or "unmaintained". Of course it has maintainers, but *BSD switch to basing itself on ZFS on Linux because they don't have enough.
TLDR: Hyperbole != wrong and nobody disagrees with the substance just with the tone.
