Deno uses regular Typescript for static type checking, it's just built-in. Bun also doesn't do type checking by itself, they recommend using tsc [2].

Until they bundle Microsoft's compiler, it isn't the same thing.

It is like tracking down if a C bug in GCC relates to developer, or GCC understanding of ISO C documentation.

Just this alone proves it isn't the same thing,

=> Deno tries to keep up to date with general releases of TypeScript, providing them in the next patch or minor release of Deno.

The “Microsoft compiler” is exactly what tsc is, and is exactly what is bundled with Deno. Sorry if that wasn't clear.
