You would severely limit yourself if you're strict about your list without nuance. GitHub is pretty much bog standard in most companies unless you're working for the few using mercurial, etc.
I work in a MS stack and most of your list is untrue for my case. We use slack for messaging, Confluence, Wikimedia, and GDrive for documentation, Google Mail for email, I develop primarily dotnet/C# apps on a MacBook pro M5, have access to all major LLM providers and primarily use Claude and antigravity.
There only thing that checks of your list is Azure hosting.
On a personal note, it has been by far one of the best place I've worked at. The dotnet ecosystem is so well developed and rich, I expect to be paid a huge premium if I ever have to deal with Java again.
The four companies that I've worked for here in Europe all used GitLab, btw.
GitHub is not git. GitHub is not an alternative to mercurial or svn.
This is like saying Facebook is the alternative to http.
