Yeah, there is half assed stuff. But it’s not what most of the big corp uses anyway. So your little dev specific use case isn’t going to get much traction.
Teams does one thing well. It can do group chats and team calls. That’s most of what people use it for. And your corp gets a discount bundle.
Usually at big corp I haven’t seen a ceo actually schedule their own calls or deal with day to day bullshit. They have a whole team of staff for that.
