That commentary proves that the guy doesn't get it or is being a willfully obtuse hater. One of the big reasons people have been gravitating toward Omarchy is because they don't want to spend hours ricing or tweaking their desktop, they want to be getting shit done after a sub-15 minute install. And Omarchy does that very well. That's what omakase and "opinionated" mean.
That sounds fine for those first 15 minutes and maybe first weeks though. What if a certain `curl | sh` fails after a month? What if I need some other stuff down the road? If anything the article's criticism makes sense from the perspective of needing to get work done, and omarchy seems to be focused more on the aesthetics. A package manager is exactly what is needed to get shit done instead of tweaking and troubleshooting stuff.
Omarchy is fine as an (opinionated) collection of dotfiles and configurations, but there are reasons proper distros are useful aside from wanting to spend time tweaking stuff or whatever. I don't see how the article talks about anything else than practical issues with it.
Omarchy is a very fast moving target at this point. I have every expectation that in the near future, they'll develop a package manager. I agree that Omarchy is not yet a "real distribution", but it's undeniable that it's rapidly heading in that direction.
