Exactly, their issue was about a drop in visits to their documentation site where they promote their paid products. If they were making money from usage, their business could really thrive with LLMs recommending Tailwind by default

AFAIK their issue is that LLMs have been trained on their paid product (Tailwind UI, etc.) and so can reproduce them very easily for free. Which means devs no longer pay for the product.

In other words, the open source model of "open core with paid additional features" may be dead thanks to LLMs. Perhaps less so for some types of applications, but for frameworks like Tailwind very much so.
