it's a reddit imported hate-train because they didn't renew certificates twice in twenty years and a bug in pamac cause the aur to be ddosed for a few hours total, to tell you how much of an empty bandwagon it is, few years back, manjaro tried to push a closed source office suite in their base installers and none of the clowns parroting anti-manjaro mantras ever mention it, they didn't think about adding it to the agreed list of accusations in the early days so their copy pasted opinions don't feature it.
