I don't think its suspicious at all. I think it filled a long standing need for some subset of current and on-the-fence Linux users of needing and wanting a really opinionated, well put together set of defaults that you don't really get with a vanilla OOTB experience on most distros.

The popularity of the various dotfiles repos proves that enough, Omarchy just turns that into an automated set up script on top of arch while regular dotfiles repos assume you already know how to, or care enough, to figure out how to install hyprland and all the associated utilities (waybar, launcher menu, wallpaper handling, etc).

Plus, generally, most people grew up using either Windows or macOS which are also very opinionated and I'd argue most users don't actually want to form their own workflows, they'd rather have something already put together to adapt into.

Myself included. Albeit I'm a macOS user, but I genuinely don't really have opinions unless something is seriously annoying, I'll change it, but otherwise I'd much prefer a set of good defaults and I'll just learn how to use them. Most of my work isn't using the operating system itself anyway, it's done within software running on it and that's where I'd rather focus my time.
