> I would assume Microsoft is using teams in house

I wouldn't. But surely there's someone here that actually knows? It does seem hard to believe their own engineers would put up with all the issues it has.

Edit: the only evidence I could find you're right was at https://www.microsoft.com/insidetrack/blog/new-microsoft-tea.... But whether it's the primary tool their devs use for communication I don't know.

Yup, almost everyone at MS is using Teams internally. When they collaborate externally they use whatever the partner prefers. For example, there is a Discord server for ReactNative contributors and collaborators with a bunch of MS folks on it. I guess it's also possible there's a Team for Meta folks to talk to MS directly but I somehow doubt it - or at least, I doubt it gets used very much if it exists :)

Really? So they have to know how awful it is. That makes its continued awfulness even more perplexing.

Really? With the exception of Office I can't think of a single microsoft product that could ever be considered "good". They have consistently crapped out sub-par products for decades. It would be perplexing if they could actually get any IM software to a good state. This is their 3rd one. They even bought arguably the best one in the world (Skype) in 2009. Which was "coincidentally" the year that Skype usage fell of a cliff.

Have you never used Visual Studio or VS Code? Would you consider C#/.NET or TypeScript to be products? Having worked with various developer-centric tools across Windows, MacOS and Linux for the last 20 odd years, if I ever felt MS consistently dumped sub-par products on its userbase I'd happily walk away and use alternatives. Teams is one of the few of their products I regularly resent being forced to work with, and would never recommend it if I were in the position to (and yes, Skype for Business would be next on the list).

Okay I concede that Visual Studio is also good.

VS code is another crappy electron app. Why anyone would want to use electron for a text editor is beyond me.

C#/.NET are crap. Especially .NET. And a programming language that is not cross-platfrom is a joke. I know they have made some efforts to get it to work on other OS's but those are just as crappy as all their other stuff.

Nothing wrong with typescript, but I don't really see it as any kind of innovation. It's just JS with some guardrails.
