The receipts that I just linked show far more than 2 mistakes. I don’t care whether they have fixed them or not, I care that they have made so many. Trust arrives on foot and leaves on horseback. Distro forks are nothing special, so why use the one with a history of bad management? Use Arch proper or any of the countless Arch forks that use the real Arch repos, which will inherently sidestep a lot of issues that Manjaro created for itself.
You say that delaying packages makes things more stable but there is a clear history of that not being the case, which has already been described in the links I posted. This is most importantly true in terms of delayed security updates. You also don’t understand how the AUR works in conjunction with outdated Manjaro packages, which will cause dependency problems and lead to breakage. This is a very simple cause and effect so I’m not sure how you think you can try to assert “everyone else must misunderstand how dependencies work”.
As for the last bit, no Arch is obviously not being hurt when Manjaro is called out. If anything I’ll bet Arch wishes Manjaro would stop tripping over itself and giving Arch a bad name. They are already sick of Manjaro users using the AUR and complaining every time it breaks their packages, and you can read what Arch’s security team thinks about Manjaro here on r/archlinux (image mirror here if you don’t want to visit that site).
