Distrowatch lists MX origin as “Greece, USA”, but likely have developers from both the US and the EU mainly.
I would not consider MX a branch of antiX. Some developers are also working on antiX so they likely share the same ideology (mainly anti-capitalism), but while antiX is explicitly affirming so, MX, instead, keeps a neutral political tone on its portal and its communications on everything non-linux related.
I had used MX and it is a well-rounded distro, totally recommended in in a computer older than a decade, you don’t like systemd, like Debian but dislike anything Ubuntu or if you like any of the specific tools they ship with MX with. Also, knowing the ideology of some of their developers, if you despise big-brother, this distro should be less likely to be compromised than, lets say Fedora or Nobara.




“Debian - older stuff for stability. Arch - bleeding edge rolling release. Fedora somewhere in the middle.” Very true. I would add that then there are a bunch of others that fill the gaps in between. For instance, Ubuntu makes Debian easier and Mint makes Ubuntu more open and TuxedoOS makes Debian/Ubuntu far more up-to-date. Then, CachyOS makes Arch more easy and gamable while Manjaro tries to make Arch more stable. Fedora is a perfect blend but those those that have a beef against Redhat/IBM (USA), OpenSUSE is a perfect blend too of the philosophies of Debian and Arch.
