There are definitely people who say "everything we do is containers" (or worse, lambdas!) and don't notice the underlying operating system. Netflix famously uses FreeBSD for their CDN but their cloud systems aren't pushing huge amounts of traffic so they can run on anything -- and Linux is the easiest, largely because it's the default.

If I'd need to hire someone for FreeBSD system administration, I guess I'd be in trouble. I did search through Upwork.com (Freelance portal, which I think represents trends for small to medium business and companies quite well) for vacancies, which gives me:
9 results for FreeBSD
2249 results for Linux
1584 results for Docker
Noting that finding good Linux-educated sysadmin/devops (if you are paying average on market) is not instant task, for FreeBSD my time prediction just doesn't work.
Starting something, smaller than Netflix scale, based on system which is hardly serviceable due to shortage of personnel, makes not much sense for me.
