I don't really agree that ML killed their business. I paid for their product early on before it was even done but they never really developed their product. I held out hope to the end of a year and ended up never using my purchase.

Compare that to shadcn, which had visible growing pains and yet reached rocketship fame. Shadcn is evidence that developers were hungry for yet another library, and it's also evidence that users were willing to tolerate rough code on the ride to maturity.

I don't believe Tailwind's component libraries deserved to win.
