Speaking for myself, I have a home server. I bought it almost 9 years ago, and the server (haswell-grade xeon) is still perfectly ok for home-server stuff, like a NAS and plex. When I set up the server, I picked CentOS 7 because I wanted a simple, boring OS that got updates for a long time. Sure, I could have used Debian or Ubuntu, and done an OS upgrade every 3-5 years, but I just wanted to avoid it.

Last year, with RH cancelling CentOS, I switched to Rocky expecting another 8+ years of updates. We'll see how that pans out.
