It's worth noting that there are plenty of ways to run Linux virtual machines/containers under MacOS (Parallels, Fusion, QEMU/UTM, Ubuntu Multipass, Docker, Orbstack,...) which largely avoid the hardware support problems of trying to run Linux on bare, Apple Silicon, metal & let you run most of the major Linux distros (which have Arm64 versions) and container systems.
Plus, MacOS is Unix so it's a relatively easy port for Linux software: A large proportion of the major open source Unix/Linux projects can be installed using Macports or Homebrew - even if there aren't fully-Mac-ified ready built packages. (TFA does mention this as one of the reasons for not bothering with Linux on Mac)
Reality is that there's no justification for buying a new or recent Mac unless you want to run MacOS - or if you really, really want ARM and are frustrated by the lack of any ARM hardware to fill the gap between Rapberry Pi-a-likes and expensive industrial server stuff.
Asahi Linux is a very ambitious project to produce a "bare metal" Linux for Apple Silicon - but it will be a constant battle to keep reverse-engineering Apple's hardware changes with each generation of M-series processors. However, even if they're always 5 years behind Apple, that's still going to be good news: In a couple of years, Apple will probably start dropping support for M1 processors - if Asahi can get solid support for M1/M2 by then, all those cast-off M1/M2 Minis could make nice little better-than-a-Pi mini servers (even if they have to use HDMI displays...)
