Agreed that is weird wording. When I look at my environment there are basically 2 kind of developers (from this point of view) those who do Net and use the MS stack, and those who don't do Net and at max worked with VS code.

I really don't know a lot of people who do anything with the MS stack. And those who do code on and for Microsoft (which already is a minority)

I personally don't know anyone who switched from Atom or Sublime to VS. Only VS users I know have been using real VS before.
