Different folks, different strokes I guess: there's no world in which I'd use an MS-proprietary language over a broadly implemented one, let alone a proprietary language changing all the time and that has a Turing-complete type system, so I don't need to complain about bloat and churn, which is the whole point of this thread.
It's open source, not proprietary at all. Suit yourself, I don't have time to deal with runtime errors when they could easily be caught at compile time. I don't care which company makes something as long as it's a good technology. This is also why I use Copilot without any of the alarm that some people on HN and elsewhere display about it.
"Open source" and "proprietary" are not antonyms. Something can be both open source and proprietary, like XUL. TypeScript is one of them. (So are the NodeJS APIs, for that matter.)
