I do. Multiple things:

Work: I need a simple easy to use system that I can configure to meet third party compliance requirements without jumping through hoops. It really excels when you can mostly use the base system there, maybe couple services. For example it's so nice to just have a couple pledge/unveil lines for example in a Go service.

Also super nice for "set and forget" style stuff. For example "I just need a HTTPS server with acme and SFTP". That's something you get out of the box with no third party packages (so everything vetted, pledge/unveil for everything, maintenance just running syspatch and sysupgrade), which is really nice.

Personal: Private mail server, family website, a quick and dirty "watching streams together" service I set up to watch stuff with people not in the same place as I am. prosody to have XMPP for friends and family.

I would NOT use it for "people throw stuff at you" use cases (Linux and FreeBSD do a far better job there). But I absolutely love it for scenarios where you want very very low maintenance. For example that private email server. I don't have time to do big upgrade plans, or "hardening" systems or reinventing the wheel. I cannot afford to do privately what I do in a day job or consulting (setting up or maintaining really rather complicated infrastructure).

I have done that many years with Debian, but the Linux world sadly is a big complex and complicated mess. That's great, when I get paid to deal with it, but annoying otherwise.

And I don't mean that bashing wise. I use Linux, I like Linux, but somehow there is a huge drive to overengineering and then building hacks and weird workarounds that become normalized until it's a proper job. Without wanting to start a flame war, but the whole Docker, Containers, Kubernetes, Helm, Orchestrators, etc. story is a lot of reinventing the wheel and a static executable like a Go service in a container, so essentially coming with a whole Linux distribution even though one never thinks about it that way is just really absurd. That's what executables, processes, etc. were invented for.

And since I've lived through the story and as mentioned make a limit, I understand how that came to be, but it feels like the industry took a wrong turn because it was cool and exciting and then (nearly) everyone decided to use that hammer for everything one could imagine to be a nail. And then the next layer came and the next and the next. But all of them doing things differently. And suddenly to have a Postgres cluster you need Kubernetes, and Helm, but also need to know both PG config and the orchestrator's config, etc.

It's a mess and the OpenBSD people somehow knew that decades before I did.
