What is this logic? "You worked on C# years ago so you must use C# for everything"?
"You must dictate C# to every team you lead forever, no matter what skills they have"?
"You must uphold a dogma that C# is the best language for everything, because you touched it last"?
Why aren't you using this logic to argue that they should use Delphi or TurboPascal because Anders Hejlsberg created those? Because there is no logic; the person who created hammers doesn't have to use hammers to solve every problem.
So it's not just that the lead architect of C# is involved in the TypeScript changes. It's also that this is under the same roof and the same sign hangs on the building outside for both languages.
If Ford made a car and powered it with a Chevy engine, wouldn't you be curious what was going on also?
Anders Hejlsberg hasn't been the lead architect of C# for like 13 years. Mads Torgersen is:
https://dotnetcore.show/episode-104-c-sharp-with-mads-torger... - "I got hired by Microsoft 17 years ago to help work on C#. First, I worked with Anders Hejlsberg, who’s sort of the legendary creator and first lead designer of C#. And then when he and I had a little side project with others to do TypeScript, he stayed over there. And I got to take over as lead designer C#. So for the last, I don’t know, nearly a decade, that’s been my job at Microsoft to, to take care of the evolution of the C# programming language"
Years later, "why aren't you using YOUR LANGUAGE, huh? What's the matter, you don't like YOUR LANGUAGE?" is pushy and weird; he's a person with a job, not a religious cult leader.

Like these? https://www.slashgear.com/1642034/fords-powered-by-non-ford-...
It's also not what anyone said.

Nope. None of those are even close to Ford + Chevy. (Ford + Mazda is well known of course).
I chose the analogy carefully.
Maybe top ten behind MSSQL, Powershell, Excel Formulae, DAX etc.
I do love F#, but its compiler is a rusty set of monkey bars. It's somehow single pass, meaning the type checker will struggle if you don't reorder certain expressions - but also dog slow, especially for `inline` definitions (which work more like templates or hygienic macros than .net generics, and are far more powerful.) File order matters, bafflingly! Newer .net features like spans and ref structs are missing with no clear path to implementation. Doing moderately clever things can cause the compiler to throw weird, opaque, internal errors. F# is built around immutability but there's no integration with the modern .net immutable collections.
It's clearly languishing and being kept alive by a skeleton crew, which is sad, because it deserves better, but I've used research prototypes less clunky than what ought to be a flagship.
If it's the latter, I think the pitch of TS remains the same — it's a better way of writing JS, not the best language for all contexts.
as you know full well, Delphi and Turbo Pascal don't have strong library ecosystems, don't have good support for non-Windows platforms, and don't have a large developer base to hire from, among other reasons. if Hejlsberg was asked why Delphi or Turbo Pascal weren't used, he might give one or more of those reasons. the question is why he didn't use C#, for which those reasons don't apply.
