Wouldn't Microsoft do the same thing when somebody copies the language and names it "TypedWebBrowserScriptbutFree"?

https://github.com/microsoft/TypeScript/blob/main/LICENSE.tx...

The license is Apache 2.0. With the trademark, they can tell everyone not to call their thing TypeScript but at this point, given the license, they can't tell them not to copy it and change it and distribute that new thing (assuming the new distributors do so under the correct conditions).
