How long have you been using Manjaro? How long had you been using Linux before you tried Manjaro? Were you using it during one of the 4 times they let their SSL certificate expire? Have you been using it for long enough to have AUR packages break because of the planned delay?
Here's the thing, Arch distros are bleeding edge, and they make assumptions about the user behind the keyboard, one of those assumptions is that you will read the arch news, for example just looking at the news in the homepage now, if you had been using budgie desktop you would have encountered a problem preventing you from updating just a few months back https://archlinux.org/news/budgie-desktop-1072-6-update-requires-manual-intervention/ . This is not serious or unexpected, in fact if I saw the error that comes from that I would immediately know what to do without having read that news, but a newbie using Manjaro and their graphical UI would just be frustrated that their system is not updating anymore. And making matters worse if they asked on an arch forum about it they would essentially be told that they're using Manjaro and should ask on a Manjaro forum, and since those are way less active it would be a while before someone told them what to do, if they ever managed to get the output to explain the actual issue. And that's just one example, Arch distros break backwards compatibility daily, it's just not expected that you'll have packages out of date, so anything you installed manually might just break, whereas other distros are a lot more careful about what they upgrade.
