Every server I’ve encountered in my professional life runs either some kind of enterprise™ Linux like Red Hat (licensed, expensive ones), Ubuntu, or Debian, or some extremely customised Linux that’s unusable for any purpose other than whatever it was built for. Dev machines run Ubuntu, or maybe Fedora or some enterprise™ Linux.
I’ve heard from a lot of startups using nixOS and your Arch flavour of the week, but I’m pretty sure that’s only used because all four people in the company are Linux turbo nerds who have managed to agree on one specific obscure Linux distro.
Business people do complain about Ubuntu, though. They don’t like automatic updates (because their weird proprietary software only works with the specific versions they picked and they can’t be bothered to actuslly fix their code) so snaps are a threat. Ubuntu Pro expanding threatens their “use software someone else pays maintenance tax for without any bill” business plan. See also: “I like Debian but I dislike the way they patch things and how hard it is to install proprietary blobs onto it”.
They want their free software to be maintained for free not because they care about software freedom, but because they’re cheap, and Canonical and IBM starting to charge businesses for the software development they do threatens that business model.
