Tailwind is a CSS framework, and some soon-to-be cancelled product from Google that shares (stole) its name isn't going to change that in my mind. Honestly, that name collision seems in poor taste. They couldn't come up with a name that's not already used by a popular open source project?
It's pretty obvious that when you prefix a product name with "Project" that's its not necessarily final. If the experiment is a success, it will indubitably be shipped under a less verbose name that doesn't collide.
