I don't think that anyone argued TypeScript is 100% sound, nor is that a meaningful goal to hit. I find TS to be a solid language that gives me reasonable confidence in my code. (The tooling is also great!)
TypeScript's main focus is IDE tooling, not correctness. Here is an example on how generics are unsound in TypeScript: http://djcordhose.github.io/flow-vs-typescript/2016_hhjs.htm...
If you want to write JavaScript with a type system focused on soundness, you should give [flow](https://flowtype.org/) a try.
