Could the domain be moved from https://unix.stackexchange.com to linux.stackexchange.com?
Linux as a term is way better known in the public compared to "Unix" by now. It fits the contents of the site far better, albeit the operating systems are GNU/Linux and Linux is technically only the kernel (but it also refers to the operating systems).
There is apple.stackexchange.com for questions about macOS and iOS - these aren't posed here.
While the site also hosts questions about Unix-like operating systems like FreeBSD, as of 7. January 2022 there are only 1,598 questions tagged "freebsd" but 34,028 questions tagged "linux" even though many (possibly even most) Linux-related questions don't have that tag (but e.g. the name of a specific distribution). Also note that the subdomain is "unix", not "unix-like".
Moreover, such questions/tags could also be split out into a separate site if that's preferred to adjust the scope of the site as an option that could be done along with the domain-change (but this wouldn't be necessary, the scope could also remain the same). This would make the site more focused (smaller scope, less redundancy with other stackexchange sites and increased efficiency due to better discoverability of questions) and make the domain-name more accurate. This also includes questions about Cygwin which could for example be migrated to superuser.exchange. Note that graphical visualizations of scopes and their overlapping could help here. The entire minority fraction of posts about *nix that aren't about GNU/Linux or also within its scope could be split out but I don't think that this would be required for changing the primary subdomain. If this is done, questions concerning bash could be in-scope here (with this being the primary or sole SE site to ask about them) and out-of-scope only if related to Unix or Solaris/... in specific.
In summary, reasons for and benefits of changing the subdomain include that it would make the domain:
- clearer (widely understood well and easily with clear distinction/s) - in these years, Linux is far better known than "Unix"
- attracting and motivating more signed-up active contributors; having linux in the subdomain could also increase identification with the site (including community-building and attracting more people of the large community of the GNU/Linux ecosystem which currently doesn't have any other modern problem-solving website)
- less confusing for general public (nowadays most somewhat sophisticated computer users roughly know what Linux means, while most of those probably haven't even heard of Unix and if they have they don't really know what it means and how it's different from Linux)
- the same reasons for why sites usually aren't named after a small fraction of content on it which non-GNU/Linux Unix-specific questions are (and GNU stands for "GNU's Not Unix") Sources for "Linux" being more popular include the number of questions here (see above and the answer below), reddit subscribers to r/Linux (717k) vs r/unix (18k), Google trends (note that the decline may be due to Linux people starting to use alternative search engines) and Wikipedia pageviews
- better describe the actual (majority of) content
- prevents confusion what the site is about
- the title is largely ill-descriptive of the site's contents as it's not called unixlike.SE or like the topic-domain of the majority of contents here
I know this a high-level meta post with substantial implications/requirements and I may not have elaborated it sufficiently so maybe it would be good if it was possible to ask about it again if this question leads nowhere and I may edit the question over time (potentially based on critical comments). A survey (sticky) of the site's users (provided with relevant info to this decision which we could aggregate and discuss here) with most weight given to the site's most constructive contributors may (or may not) be a good or better approach than this question or a good complementary thing to do before implementation.
Edit: downvoters may have misunderstood this question to be about changing the scope of the site, however this was only proposed as an option to do along with (or after) changing the subdomain, not a necessity (the scope could remain exactly the same; this could be discussed separately even after a subdomain-change got decided).
I don't think there are good reasons to not change the domain except potentially technical/meta/non-principle issues such as search engine indexing(?) Here is a Q&A about why the site has the current domain. It suggests that both users "didn't have any say in that" and that it seems like not a lot of thought has been put into which domain was chosen.
