Sure, but to complain that a Mac, which, come on, at this point is a known quantity for 20 years, doesn't run Linux is just looking to complain. If you want more options there's endless x86 choices, and if you want ARM then demand better from other manufacturers as well. Apple showed its possible, why doesn't Dell come out with something comparable? I'm not a fanboy, I run systems of all stripes, but Macs aren't designed to be servers (even though they operate perfectly well as one) and people need to stop complaining that they aren't.

I run full multiple Ubuntu desktop VMs on Parallels on a M1 MacBook Air. You can use Docker for server installs, sure, but QEMU also works great on Macs and with Rosetta you can even get pretty damn close to native x86 execution speeds.
