I can see it now:

> Most C libraries do too much.

> They come with all sorts of predesigned components like functions and structs that might help you move quickly at first, but cause more pain than they cure when it comes time to make your program stand out with custom behavior.

> Tailwind C is different.

> Instead of opinionated predesigned components, Tailwind provides low-level utility macros that let you build completely custom functionality:

    void main() {
        BEGIN_TAILWINDC
        MOV(RAX, 4);
        MOV(RDI, 1);
        MOV(RSI, "Hello world!\n");
        MOV(RDX, 13);
        INTERRUPT(128);
        END_TAILWINDC
    }

And then every Hacker News discussion of Tailwind C would inevitably include a link to their "Why using Tailwind C is definitely not just as bad as writing inline assembler" documentation page.

Ooh, and then the creator of Tailwind C would start selling the Tailwind C Library, with like an implementation of memcpy that you just cut-and-paste into your program every time you need to copy memory.
