I understand you're not a fan of Tailwind, so perhaps say what you dont like about Tailwind instead of creating a strawman and attacking it.
Also, shame on you for poo-pooing on someone else's open source project and people find useful.
> poo-pooing on someone else's open source project
This is not some young kid doing free software out of kindness. This is a company making millions of dollars in revenue in a closed source product (tailwind UI), which is built on a foundation (tailwindCSS) that is becoming less and less needed.
As someone who's done it both ways with web sites, that separation sucked. Having to figure out which style in my CSS file was messing things up was always a pain. And Tailwind tends to be "local" by default, limiting the damage done to other elements when I style an element.
In my larger experience (not just with web sites), whether separating content and presentation is a good idea varies widely from use case to use case.
