Nah.

Tailwind provides an actual simplifying layer for the (over-)complicated practice of front-end web development.

By being well-though-out, well-designed, and very well documented, it actually made web app styling easier/simpler (without hiding or otherwise making it hard to drop into CSS as needed). And it slotted right into the place most web apps have for a CSS/class mechanism.

The paid templates extend the approach to components. The business model is that the credibility they establish with the free high-quality CSS/class system makes people willing to pay for the templates, which then goes over well because the templates are good and useful, saving a lot of development time. BTW, their templates solves a different problem than native components -- I suspect you're dismissive of their business model due to not actually understanding it.

Of course, it's all moot now. AI can generate the components now at the same time it's doing everything else, so no reason to pay for their templates. (Plus, tailwindcss probably doesn't build the credibility as much anymore either because devs aren't using it (their AI might be, but without the direct contact it doesn't have a chance to build that open-the-wallet credibility.)
