Very sad to hear, I bought Tailwind UI years ago and although it was a lot more expensive than I wanted, I've appreciated the care and precision and highly recommend buying it (It's now called Tailwind Plus) even still (maybe even especially now). Mad props to Adam for his honesty and transparency. Adam if you're reading, just know that the voices criticizing you are not the only voices out there. Thanks for all you'…
It was never sustainable as a product/business, as this pricing model requires constant growth. What I've seen along the way was a heavy pivot towards React (which left me wanting: I mostly use the Vue components & the HTML/JS components with Astro.js in the projects I work in) and even in the case of React, they haven't managed to arrive at a full, mature component library offering (while others have!).
TL;DR: I'd be struggling to justify it as a purchase for a new user now, even before factoring AI in.
