keep in mind that css tricks is much more of an actual community resource than omarchy ever was, and has an AI statement that is, in short, "we don't use it".
even if we entirely set DHH's fascism aside for a moment, then omarchy is the kind of distro more or less anybody could run on a low budget: heavily piggy-backing off of another distro (in this case arch), with some super special customizations to set it apart. the fact that someone can easily get multi-million funding for this with relatively short negotiations while something like css tricks gets defunded (and other FOSS projects going largely un- or underfunded) leaves a bad taste in my mouth. not because this kind of piggy-back distro doesn't have value, but because it's such a crass and bizarre misallocation of resources.
DHH is throwing other projects under the bus here; he could also use his good connections to convince CEOs that other projects are worth funding as well, and he isn't doing that. DHH is the epitomy of "got mine, fuck you".
