Good news. Hopefully this will help to finally break the de facto monopoly of Microsoft’s GitHub and bring the distributed aspect of Git - away from gatekeeper platforms - back into the foreground.
Linux is probably not the wisest choice for gaming - that would still be Windows. Anyway, the distribution does not matter that much. You can install most Linux and cross-platform software on most distributions. Do not choose your system because of what comes as the default desktop, default package set et cetera. Try a few ones. Read some reviews.
It depends on what you want to achieve. MX Linux is one of the less annoying Linux distributions (although I’m more into Void and Slackware, to be honest), but in terms of privacy (which is the very topic of this Lemmy community), it doesn’t do much better or worse than most other Linux distributions.
