Really doubt any of the information is true. I bet the ad was created by men with seriusly messed up assumptions.
Discovery got even worse after season 2.
Very nice. I've been daily driving KDE for 20 years and only changed the default wallpaper once or twice.
Not sure it satisfies your requirements but I'm quite happy with Baïkal.
Borg is great.
This was just an outline of what you could do in the scenario, not a full solution. Looking up the keywords, "Apptainer" (+sandbox), ".sif", and "AppImage" should give you a starting point, and any specific questions can be answered separately. You are right that people could be jerks to beginners but this is rarely the intent. Not all discourse about Linux has to be at a beginner level, and packaging legacy software is not really a beginner topic.
Not sure this statement is true if "more closely related" is understood as shorter combined time between the two species from their most recent common ancestor. Hummingbirds and brachiosaurs had a more recent common ancestor than brachiosaurs and triceratopses (albeit probably still quite close to the dawn of dinosaurs in the Late Triassic ), but the latter pair lived closer in time to the common ancestor of all dinosaurs (while hummingbirds are from the Oligocene).
