Meanwhile Fedora‘s (Red Hat) dominance is never even questioned.

Huh? Pretty sure it's constantly questioned, especially by those who reject systemd. Sometimes that isn't hate, but well-reasoned (but occasionally badly worded) rejection.

The hate some have for Ubuntu and Omarchy is ridiculous.

Wasn't Omarchy made by a fash, TERF or some other kind of extremist? Harmony is great and all, but like with tolerance it can't be absolute.

Ubuntu gets their well-deserved amount of criticism in my eyes since they still haven't published the damn Snap server source code (afaik). A distro that had such great ideas in the past like including Amazon ads inside the desktop or silently symlinking apt commands to snap have to do a better job to regain community trust, instead they reject efforts like Flatpak or AppImage and build partial closed-source.

I like harmony too, but please don't attempt to deligitimise well-reasoned criticism.

Imagine defending fashtech

I'm confused on why you think ubuntu and omarchy can't also be part of that "culture" you describe. It's also a bit different for omarchy. Part of it is that it's just another arch flavor that isn't all that special, but everyone started talking about it all of a sudden, which made people grow tired of hearing about it pretty quickly (kinda reminds me of what happened to ghostty tbh). The other part of it is its creator being a conspiracy weirdo, which puts people off.

I'm against it lol.

I think anyone that doesn't realise there is not "best" in distros is either stuck in the consumer mindset or is so narcissistic they think everything they do is the best without ever considering that perhaps few people are actually like them.

Truth is, there's a distro for everyone. It's super easy to test drive and hop. We're spoiled for choice. If someone wants to contest someone else's choice, they're an idiot and can go back to closed source where over-researching and min-maxing is a requirement to get what you want, not a choice.
