It's the first time I heard that, though I admit I'm not really actively involved in any type of TS community. All I've been in contact with are the TS releases and blogpost from the TS development team, for which I can only give credits (quite fast and stable development with good features), and some TS projects and definition files for existing libraries I found on github which were pretty decent and helpful. As naive as this question may be, can you tell me more about what parts of the ecosystem or which community you mean?
Ah yes, true. I've always thaught of it as understandable that they focus on Visual Studio, but I too would much appriciate it if they would push that a bit less. I did try the free version of VS when I started with TS, but I didnt prefer it to webstorm, even though in some small details, the ts support may be slightly better.
