Specifically, do you worry that Microsoft is going to eventually do the Microsoft thing and horribly fuck it up for everyone? I’ve really grown to appreciate the language itself, but I’m wary of it getting too ingrained at work only to have the rug pulled out from under us when it’s become hard to back out.
Edit: not really “pulling the rug”, but, you know, doing the Microsoft classic.
If it makes you feel a bit better, think of it this way: Typescript is open-sourced not to just get the public free-access to it, but also for the public to provide feedback and improvements. Without outside devs to report bugs, TS would be living [ and dying ] in its own bubble.
This is almost™ the same tactic Apple uses for Darwin by making use of netBSD’s open source nature.
